 Running In Elderly Promotes Walking-Economy of Youth

Older runners had a 7–10% better walking economy than older walkers over the range of speeds tested (p = .016) and had walking economy similar to young sedentary adults over a similar range of speeds (p = .237). We found no substantial biomechanical differences between older walkers and runners. In contrast to older runners, older walkers had similar walking economy as older sedentary adults (p = .461) and ~26% worse walking economy than young adults (p<.0001).

 An Algorithm for Predicting Longevity

For the test, participants exercised on a treadmill at increasing speed and incline. While they were exercising, the researches measured peak heart rate (%MPHR) and their ability to withstand physical exertion. On that latter point, they measured metabolic equivalents, or METs, which gauges how much energy the body expends during exercise. The more intense the exercise, the higher the METs (e.g. slow walking = ~2 METs, whereas running = ~8 METs). [...] FIT Treadmill Score = %MPHR 12(M...

You can get your MPHR for your age here. I found a chart of METS here for various exercises.

Activity METS Activity METS
Aerobic Dancing 6.0 Running 12 min/mile 8.5
Backpacking 7.0 Racquetball 8.0
Badminton 7.0 Rugby 8.3
Basketball 6.0 Skating ice/roller 7.0
Bicycling - 24mph 5.0 Skiing cross country 8.0
Calisthenics 4.5 Soccer 8.0
Golf 5.0 Softball 5.0
Gymnastics 5.5 Swimming 6.0
Handball 8.0 Tennis 7.0
Hockey 8.0 Volleyball 4.0
Horse riding 3.5 Walking 3.5
Running 8 min/mile 12.5 Weight lifting 4.5

2 3 12 4.0 2.5 7
3 3 14 5.4 3.4 10
4 3 16 6.7 4.2 13
5 3 18 8.0 5.0 15
6 3 20 8.8 5.5 18
7 3 22 9.6 6.0 20

Total Durations = 21 minutes

So, if I'm understanding this correctly. If I reach a 160 heart rate out of 179.0 MPHR predicted for my 41 years of age while running 12 minute miles worth 8.5 METS. My score would be:

83.7 12(8.5) - 4(41) = 21.7

The same heart rate for my age running 8 minute miles:

83.7 12(8.5) - 4(41) = 69.7

 Understanding Awe

It can be hard to generalize what people consider jaw-dropping, but Vohs says research demonstrates what consistently creates an awesome experience. Travel ranks high. So does gazing at the cosmos on a clear night or watching a sensational film, as well as anytime we encounter massive quantities: colorful tulips in bloom, a bustling market in India, or a stunning school of fish. Novelty and perceptual vastness forces us into the present moment. The study underscores the importance of cultiva...

The sense of wonder has health benefits, may open us up to learning new information, but what is it exactly?

 Being in a Car Affects Our Sense of Personal Space

Psychologists have noted that people driving a motor car react in a manner that is often completely unlike their normal social behaviour as regards their territories. It seems that a motor vehicle sometimes has a magnifying effect on the size of a person’s personal space. In some cases, their territory is magnified by up to ten times the normal size, so the driver feels that he has a claim to an area of 9 to 10 metres in front of and behind his motor car. When another driver cuts in front o...

The car magnifies our personal space perception, making us angry when others violate it.
