On: Exercise should be kept to a healthy minimum

[smegel]

Find some 20 years old cars, one with 200,000 miles on the clock, one with 20. Which would you choose?

Humans aren't cars...? Don't use an analogy unless it has a logical basis.

[ldp01 → AppeasingRoko]

Parts of the analogy are certainly correct...

Mechanical parts wear out from use, whether they are animal or machine. Animal parts will heal to an extent and may require a minimum level of use to stay healthy, but they still wear out.

You're right. It is much easier to repair a car.

[brianwawok → smegel]

Car's don't self repair.

If I go lift heavy weights, my bones self repair and get stronger.

If I sit on my butt all day on a computer, my bones get thinner and weaker.

No matter how much you drive a car, it is never going to get "stronger", only slowly wear out.

Since you are a human and not a car, I would suggest you maintain your body like it is alive and not made of metal.

In both cars and people I would ask the same thing: is there a 25-35000 miles option too ? Too low is worse, and 20 is a sure indicator of big problems. So is 200,000.

As to the general feeling here. I invite everyone here who thinks ridiculous exercise is good to volunteer at an emergency room for a week. I guarantee this idea will get cured on the first day in any large city.

Humans are cars that run constantly. So the human analogy to a car with 20 miles would be a baby.
