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).

1 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 |
| Stage | Minutes | % grade | km/h | MPH | METS |
|---|---|---|---|---|---|
| 1 | 3 | 10 | 2.7 | 1.7 | 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

Dolphins have Genes for Smelling
Another curious tale of dead genes involves our sense of smell, or
rather our poor sense of smell, for humans are truly bad sniffers among
land mammals. Nevertheless, we can still recognize over 10,000 different
odors. How can we accomplish such a feat? Until recently, this was a
completely mystery. The answer lies in our DNA—in our many olfactory
receptor (OR) genes.
[...]
Our own sense of smell comes nowhere close to that of mice. One
reason is that we express fewer OR genes—only abou... 1

Fetal Alcohol Syndrom
It is from a public health standpoint, rather than from knowledge of indipercent of pregnant wompr. i^ percent of pregnant women in the United States reported drinking alcohol in the month preceding the survey, and 3 percent admitted to at least one binge. (Alcohol consumption is notoriously underreported in this kind of survey.) Prenatal alcohol use is thought to be responsible for at least 4,000 cases of mental retardation in the United States each year and perhaps ten times that number of ... 1 notes
