If there's anything the history of scientific experiment and research
demonstrates, it's that so-called "common sense" is an unreliable
indicator of physical truth.

No, one does not disprove the other. There may be other factors
involved in height which adolescent weight-training affects
negatively.

Sure, that's certainly the case. But that does not prove that teenage
weight-training doesn't stunt height.

No they don't. Muscles stop contracting, but it ain't due to lack of
ATP in 'em, nor due to lactic acid build-up (indeed, lactic acid
concentrations decrease at a certain point during continuous
exercise).

No stretching -- ballistic, dynamic, etc. -- has been found to be
beneficial. The point is, physiology and exercise science is at an
infant stage still.

There is such great variation that it really makes no sense to claim
to know eternal truths.

Correlation is not causation. Are we a more lawful society because we
have so many lawyers? Are the Chinese more technologically advanced
because they produce many more engineers?
