Harry's Pieces

 
Welcome to Harry's Pieces. Below are some inspiring and informational pieces written by Henry Lodge, M.D.
Open call for limbic resources !
Chris and I would like to begin collecting what we call limbic resources. These are organizations, mostly non-profits, that offer effective vehicles for Younger Next Year members to get connected, do some good, and build their limbic base. I will share a short story to get the ball rolling. I was sitting with a very nice guy this weekend at a lunch, while picking up our respective daughters from camp. He told me that back in the late 80s he had found an organization called Earthwatch ...[read more]
Biking a spontaneous century
I am up in Lake Placid for a few days, and brought my bike along. I went out yesterday for a ride, on a day that was threatening rain the whole time, but never actually did. When I looked at the map before setting out, there was a nice 60 mile route, but it involved taking a lot of back roads, and I'm new to the area so I didn't relish the thought of getting lost all by myself on a rainy day. Accordingly I mapped out a straightforward out and back route going up from Lake Placid to Saranac an...[read more]
Breathing pollutants when exercising outdoors
Terry wrote: Harry, I've read your book twice and listened to the CD's multiple times in my car. In Phoenix we have a mountain (Squaw Peak) that is 1,200 feet high. When I was 33 I could run up it in 18 minutes and 45 seconds. I've climbed it well over 1,000 times. Now I am 62. At this age I can jog up in 24+ minutes, with a max heart rate of 160-164 bpm, but this requires a lot of seriously heavy breathing. I just don't think my lungs are working as well now as they used t...[read more]
Why your resting heart rate matters
RESTING HEART RATE People often ask how to gauge whether they are working hard enough, or too hard, as an overall issue, as they go forward with six days a week. This is an important question because it is surprisingly easy to over-train. Normally, in the inadequate American scheme of exercise, we do three or four work outs a week. While not enough to give you optimal fitness, this does have the slight advantage of giving you an enforced full rest day between most of your workouts – thereby...[read more]
Striking the balance between strength and fitness
One of the questions that comes up as people get further along in their own exercise programs is the relative merits of doing strength training two versus three days a week. There is no right or wrong answer to this. It’s purely a question of what you are looking to get out of your fitness program. As long as you stick with six days a week, either one is fine, but they will leave you with mildly different benefits. The key thing to remember about strength training is that, done right, it e...[read more]
Light Aerobics vs Hard Aerobics
Light Aerobics vs. Hard Aerobics Any form of regular, aerobic exercise is good for you, but you can get more mileage out of your exercise if you understand the difference between burning fat and burning glucose. That's the key to really effective aerobic exercise, because different exercise intensities trigger different biological changes throughout your body. You have two natural aerobic paces, easy and hard, and they depend on two very different muscle metabolisms, which are determined by...[read more]
Harry's Guide to Heart Rates
Harry's Guide to Heart Rates Step 1: Finding Your Real Maximum Heart Rate Step 2: Keeping Track of Your Resting Heart Rate Step 3: Must-Know Heart Rate Facts Step 4: Respecting Your Limits Step 5: Preparing for Hard Exercise Step 6: Assessing Where You Are Finding Your Real Maximum Heart Rate The "220-minus-your-age" formula is a rough and often inaccurate guide to individual heart rate. While it's good enough for getting started, it's not good enough for guiding you through the lo...[read more]
Cold Weather Exercise and Physiology
COLD WEATHER EXERCISE I have been skiing up at Stratton, Vermont, and yesterday the temperature was minus five at the base and minus sixteen at the summit, with 25-mile-an-hour gusts, which translates to a wind chill of minus 45. I skied perfectly happily all day, albeit with a couple of breaks for cocoa, and it led me to think a little bit about outdoor exercise in extreme cold. I will talk about the physiological adaptations in a moment, but the first adage is “There is no such thing as...[read more]
Harry on: What do you want to hear from me ?
I am going to post pieces on the science of lifestyle, but wondered if there was an audience for other pieces on more abstract (or abstruse) science as well. There is a lot happening in evolutionary biology, and in all sorts of areas of science that interests me, but I don't want to write about it unless there is interest, so please let me know ! THanks, Harry[read more]
Harry On: Good Gear
HARRY ON GOOD GEAR Chris makes a strong point in the books about the importance of getting good equipment to see you through on this journey of perpetual fitness and youth. I have been more of a skeptic on this, because of my New England roots – (the joy I take in spending the least possible amount of money). I actually still think that is a wonderful way to approach the subject, but there certainly are areas where it makes sense to get the gear that’s right for you, and I think the areas...[read more]
Extreme Aging
The Old Old From 80, or 85 onwards you enter a new territory. Though there are certainly avid skiers and runners in this age range, the natural process of biological aging has become a clear factor in agility, strength and stamina. Interestingly enough, while its harder to engage people in the concept of themselves as natural athletes in this age range, the stakes, and the rewards are higher than at any other time. Until now, being fit and strong has been about enjoyment, now it’s about the f...[read more]
Winter Dehydration
Dehydration for all seasons: Most of us are well aware of the risks of dehydration on blazing hot summer days, but what about the rest of the year? Dehydration is a significant issue in the winter as well. It’s not accompanied by the risk of heat exhaustion or heat stroke, so the medical risk is far lower, but you can bonk, and badly, if you don’t understand the risks. The first risk is that of pure stupidity, combined with travel to warmer climates during the colder seasons. Allow me to i...[read more]
