In Defense of TED

There was some TEDMED bashing going on in the comments to an article in the Washington Post, and I felt compelled to come to TED's defense. My comment raises an important point about communication and promotion of science to the general public—a topic near & dear—so I'd like to re-post it here and add some follow up thoughts.

The situation: some scientist types in the comments were slamming the whole TED enterprise with statements like:
TEDMED is for self-promoters, not scientists. 
Real scientists don't have time for this.
No working scientist in the field of human genetics pays attention to TED...in any form. 
My reaction:
Have to disagree. Science needs the TED hype machine, big time. Events like TEDMED provide a worthy service in promoting science and showcasing scientists to the general public. Scientists can use all the PR help they can get in making their work exciting and connecting with the masses (which funds most research here in the U.S.). 
TED encourages more public engagement in science & technology -- something that is especially important now given the trouble we're having with basic science literacy and graduating more science and engineering majors.
Real scientists should appreciate anyone talking up science, especially high-profile figures that have the broader cultural reach practicing scientists can't attain (since they're busy doing science and cranking out those papers). 
Yet science spokespeople that don't have sufficiently scientific credentials are frequently dissed by the scientific elite. Recent example: Alan Alda on Science Friday was dubbed by a caller as an "offense to science" since he's not a trained, practicing scientist.
Real scientists may be too busy doing science to pay attention to TED, but millions of real people do tune in, and that's real good, IMHO.
And BTW, there were some real scientists at TEDMED2012: Eisen, Petsko, Butte, among others.

Jack LaLanne Thoughts

Today marks one year since Jack LaLanne passed away. I want to use this space to collect some thoughts on his life and legacy. This is at present just a preliminary post. Stay tuned for updates.

The image at right is from the LATimes collection of 'Notable deaths of 2011'. Their obituary was one of the best out there and is one of many that came flooding in from every major new source after Jack died on 23 Jan 2011.

Regarding the "for the record" note in the LATimes obit regarding Vic Tanny opening a gym before Jack did: Jack actually started a gym in 1931 while still in high school (mentioned in the Larry King interview video clip below). He trained policemen and firefighters and was the first to have progressive weight training.

Words with Larry King 

Jack gave a great interview with Larry King on 17 July 2000 when he was 86 (see the complete transcript and a short video of a portion). Here are some JLL quotes from that interview that sum up his main messages about health & fitness:

• "If man makes it, don't eat it. Stick to as close to nature as you can."
• "It's not what you do every once in a while, it's what you do every day."
• "I have never really liked to exercise but I like the results!"
• "Exercise is king, nutrition is queen, put them together you've got a kingdom."
• "Anything in life is possible. Make it happen. It starts in your brain. There's really no limit. The limit is between your ears."
• "You help you. We must take responsibility for ourselves."
• "You don't die of old age, you die of neglect."
• "I can't afford to die, it'll wreck my image."
• "Break the monotony of your workouts. You're doing something different, you're muscles respond, you prevent injuries."
• "If you're overweight, you have to count calories. Period."
• Regarding daily workouts: "Everyday I don't want to do it. But I kick the devil off my shoulder, 'Get outta here!' and I workout. The next thing I do is I look in the mirror and say, 'Jack, you've done it again!'."
• Message to today's youth: "There are two things in this life that you have to develop: pride & discipline."
• "You've got to use every joint in you're body. Completely extend & contract."
• "Always keep your stomach tight."
• "Your health account & your bank account are synonymous: the more you put in, the more you can take out."
• "So many of you people are lounging, just sitting there on your big backsides, and you're fat and out of shape, and you're praying to God, 'Dear God, please!' God is not going to do anything, you've got do it! God gives you the power to do it. God helps them that help themselves, and I hope that each and everyone of you helps the most important person on this earth, YOU!"

Jack LaLanne Day

For the past several years, I've been promoting the idea of designating Jack's birthday (26 September) an international day of health. I've also been leading free, monthly core workouts for JLL "check-in" days in the SF Bay area, since one day per year for fitness doesn't really cut it. See JLLDay.org for details.

More to come...

Apple Devices Power Down

...and observe a moment of silence

...Your time is limited, so don't waste it living someone else's life. Don't be trapped by dogma, which is living with the results of other people's thinking. Don't let the noise of other's opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary. 
...The only way to do great work is to love what you do. If you haven't found it yet, keep looking and don't settle. 
...Stay hungry. Stay foolish.   --Steve Jobs, June 2005, Stanford

Green Tech Oy Vey!



Sometimes you just want to crawl under a rock, particularly when your DC-AC power inverter's low voltage alarm goes off for the N-th time in the middle of the night and wakes up your neighbors. Such is the plight of this greentech do-it-yourselfer.

Let me explain.

Since early 2008, I've been playing with a mini-solar power system that I set up at my house. It started out with just one panel, one deep-cycle battery and a cheap 400W inverter from Radio Shack but has grown to 7 panels, 3 deep cycles, and a 600W pure sine wave inverter (needed to convert DC from the battery into AC used by appliances). At peak sun, it can generate 35-40 amps -- not nearly enough for a family of four to live off the grid, but enough to keep the batteries charged and power a handful of small gizmos, the sort that come with a "wall wart" AC converter (e.g. modem, router, phone rechargers, laptop recharger, printer, even a small desktop computer + monitor with good sun).

I need to keep the inverter turned on around-the-clock because I am using a timer to control when the connected appliances are on, so they don't drain the batteries overnight (there's no need for your wireless router to be on at 3am, at least not most nights). The use of a timer necessitated the pure sine wave inverter, since the timer needs a nice-looking wave form to keep track of time accurately. The cheaper inverter produces a 'modified sine wave' (actually a square wave) -- poopy from the point of view of the timer and some appliances like computers/monitors, which will be noisier with it.

Sounds peachy so far. What's the problem?

Because space is tight inside the house, I've had my entire set up outside: panels (duh), batteries, inverter, etc. Handily, I can connect the inverter to an indoor 6-in-one power strip via an extension cord running under a door. Weather is mild year-round in the Bay Area, so it's not too rough on the batteries, which are protected from rain & sun. However, my batteries have grown decidedly less happy over the past three years (and yes they are protected by a charge controller to avoid over charging). My upgrade to the 600W inverter which draws more baseline current than the cheapo 400W unit has meant that there is more load on the batteries even when it's not powering any appliances.

Enter the low-voltage alarm.

A handy feature of the inverter is that it will sound an alarm when the battery charge drops below a certain point (10.7V). This is to warn you about the situation before it shuts down, which it will do when the battery voltage drops even further (10V), to avoid damaging the batteries.

Sometimes, due to cloudy/cool days or lots of indoor appliance use, the batteries don't sufficiently charge during the day to make it through the night (even when the only load on the system is the inverter itself) and the alarm will trip at some random point between 2am-6am. Other times, such as when I'm working late, I will temporarily extend or disable the timer and will forget to re-enable it later, meaning the appliances will be continuously running and likely will drain the batteries before morning sun or on the following night.

Then, the low-voltage alarm trips...

Now this alarm screams like a banshee, and it annoys the bejeebers out of our neighbors (who often have windows open at night). We, on the otherhand, don't hear it because we sleep with our double-paned windows closed and often have an air filter running, too. The alarm went off in the wee hours this AM, and zapped our neighbors from their slumber yet again. I'm truly sorry for this and have another wine bottle peace offering at the ready.

But there is good news.

This morning, after the latest 'incident', I moved the inverter indoors out of neighborhood airspace. This meant a less than optimal battery-to-inverter connection (via 10 AWG wire which fits under the door, unlike the 4 AWG wire I had been using). So the next time the inverter blasts it will just be us that are annoyed.

I had been researching ways to disable the inverter's alarm, but as far as I can tell, this is not possible (and probably not a good idea to do so).

Ideally, the batteries + inverter should be kept in a more controlled environment, like inside the house, allowing them to hold their charge better and keeping the inverter out of earshot of neighbors. I could also ditch the batteries altogether and invest in a grid tie to PG&E's power, but I'm (1) trying to keep costs down and (2) like the fact that I can run without any grid dependency.

Someday we'll buy a real solar installation, probably from my friends at Sun Power, and my jury-rigged solar install will be a thing of the past.

Barefoot Running


I got some Vibram 5 Fingers (VFF) shoes at the end of December 2009 and during the past 4 months I've been experimenting with running in them, to get my feet wet in this barefoot running business that has been much in the news of late. (Technically-minded folks will note that if you're wearing these shoes you're not barefoot, but you're pretty darn close.)

I'll use this post to provide some background links as well as describe my first-hand experiences. I included a couple of self-photos of my KSO's: the first shot was taken during the first week I had them, and the second was taken about 3 months later, after wearing them during the run portion of the Golden Bearathlon. It was a muddy 10K trail run and the shoes cleaned up nicely in the wash. I don't do all my runs in these shoes now, but I'm gradually moving in that direction.

Goodbye Orthotics

Probably the most powerful thing I can say from my experiences would be this: Since I started running in the VFFs, I have dropped my dependency on the custom orthotics that I've worn religiously for the past 15 years. In 1995, I had the orthotics made and wearing them greatly reduced my running injuries; basically I never did a run or went anywhere without them since '95.

However, this has all changed since I've been running in the VFFs. These minimalist shoes are basically socks with some rubber on the soles -- you cannot wear orthotics in them (well, you could, but it would feel very clunky and biomechanically unnatural). So I've stopped wearing the orthotics whenever I run, even when I run with regular, heavy-soled running shoes. I have not encountered any chronic running injuries since, and I no longer need to worry about where my orthotics are at all times (though I still prefer them if I have to do a lot of walking/standing, e.g., spending the day at Disneyland).

Gradual Adaptation

I've been running for fitness for the past 30+ years wearing conventional, cushy, industry-standard running shoes (usually something neutral like the Asics Gel Nimbus). Since running in the VFFs, it's become apparent how woefully undertrained my calves were. By promoting a rear-foot strike (RFS) running form (i.e., landing initially on your heel, then rolling off the toe), standard running shoes effectively shield the calves from doing much work.

Before I acquired the VFF shoes, I spent 1-2 months working on a more fore-foot strike (FFS) running style using my traditional thick-heeled running shoes. This included some barefoot running on grass. I experienced lots of calf soreness during this period, especially after harder, faster training sessions. It took a while to switch my running form from RFS to FFS -- I'd say a solid two months before it started to feel natural. I was lucky enough to get some great coaching from local track coach Steve Kraft to help me learn this new running style, which has more elements to it than just foot strike.

Once I got the VFFs and started doing faster and longer runs in them, my calves experienced even more soreness. I took it fairly easy, running only on soft surfaces (like trails or rubberized tracks) once every 1-2 weeks in the VFFs, using my standard cushy shoes for all other runs. The first time I did a mile's worth of total speedwork in the VFFs, my calves were sore for a week, hard to walk or even bike for the first few days after. Additional feedback on my VFF running form from other experienced runners revealed that I was running too much on the balls of my feet, putting excessive strain on my calves. With practice, I was able to adopt a more neutral foot strike.

Morals: 
  1. Be extremely gradual in adding speed and mileage to your VFF runs.
  2. Get some feedback from a running coach or experienced runners.

Update, 19 May 2010: Here are a few additional thoughts and tips on barefoot or minimalist shoe running:

Are they comfortable?

This is the most common question I get from random, inquisitive strangers that notice my VFFs when I'm out in public with them. In short, yes they are quite comfy when just lounging around in them. But note that they give about the same degree of support as a pair of socks, so spending a full day standing/walking around in them on pavement will really wipe you out the first time you try it. About two months after I started wearing them I spent two back-to-back days wearing them while visiting Disneyland with my family -- this was definitely overdoing it.

The lightness of being barefoot

The lack of weight at the end of your legs while running is quite addicting. It leads to much less torque on your overall leg motion and permits a more natural gait and more efficient cadence. The low weight and lack of bulk of the VFFs also makes them highly portable. I actually biked with them in a fanny pack, along with a bunch of other gear, for the entire MS150 bicycle ride from Houston to Austin in April 2010. They were my après-cycling footwear.

Running shoe built-into your legs

Barefoot-style running trains your leg muscles, feet, joints, and connective tissues to learn to do more of the shock absorbtion that we've been delegating to conventional running shoes. Running barefoot or with minimalist shoes like VFFs trains your legs to acquire those shock absorbing powers, essentially building a running shoe into your body. Transitioning from a RFS to a FFS style and adapting to minimalist shoes feels like it has given my running legs another "gear" that I can employ regardless of my footwear. It is a more muscular style of running where the legs learn how to absorb the shocks of running and even obtain some elastic recoil from each foot strike. With a RFS running style where the shock of each footstrike is dissipated via the heel, shocks are absorbed primarily via the shoe plus your skeleton, which dissipates the impact energy and provides no recoil opportunity (and can in fact lead to loss of forward momentum via braking).

Easy does it

As Barefoot Ken Bob warns: Don't do too much too soon! There's a strong temptation to overdo it, especially as your feet and legs start adapting. But it really takes quite a bit of time to fully adapt to a barefoot or minimalist shoe running style. The transition is more difficult and longer for folks (such as myself) with a long history of RFS style running.

When starting out, pick the smoothest surfaces you can (such as grass, astroturf, or a rubberized track). Our soft, modern feet take a major pounding when running and bruise/blister incredibly easily. The first time I stepped on a rock the wrong way with the VFFs I got a bruise on the ball of my foot that was tender for several days, and even after 5 months of using the VFFs, I still get hot spots and bruises when I push the pace or terrain (though my feet now recover much faster). Over time, you will learn how to run more gently and your feet will toughen up, but it takes months (maybe up to a year), and you still must always be mindful of your terrain. The plus side of having barefoot/minimalist shoe running is it provides great feedback from the running surface that is otherwise masked standard heavy-soled running shoes. Especially when running on trails, each footstep is unique, giving you a deeper sense of connectedness with your environment and increasing the mental stimulation of running. It can be very reflexology-like. Run barefoot for best results here (feet and terrain-permitting).

Variety is the spice

Even if you are skeptical about the benefits of barefoot/minimalist shoe running and think it's yet another passing fad, you've got to admit that it is way different than what the running shoe industry has been doing for the past 30+ years and it gives a runner something new to play with. This helps inject variety to shake up your routine, get you out of your comfort zone, and can help keep your workouts from becoming stale. This all helps to keep you motivated, which is key to long-term success in sticking with your fitness goals.

Foot stretches.

Helps with tired feet, especially when walking/standing in them for long periods. Here are some stretches, all of which can be effectively performed while wearing VFFs (but not with standard shoes!):
  1. Flex and point toes, alternating and holding the stretch and point for ~5 seconds each.
  2. Foot circles or "alphabets" where you trace each letter of the alphabet with your foot (caps or cursive).
  3. Gripping with toes. Imagine you are trying to grab a ball with your toes. This motion is almost like pointing your toes while dorsiflexing. 'Grip' and hold for a few seconds. Relax by dorsi-extending and fanning toes.
  4. Top of toes on ground. Can be done when standing or sitting. Standing on one leg, bend other knee and point toes behind you, attempting to touch the top of foot on the ground behind you. Hold and breathe.
  5. Foot massage. While sitting, cross on leg and work one foot at a time. Use your thumb to massage the plantar fascia. Also massage the lower achilles tendon area around the sides of the heel.

Use powder

Applying talcum powder on the inside of the VFFs helps a lot in fighting microbial odors and easing foot entry. I like Burt's Bees; Dr. Scholl's also sells powders with antimicrobial additives. Washing the VFFs with a powdered detergent once/week on a gentle or 'easy care' cycle then air drying keeps them in good shape. Just throw them in with your other laundry.
