Exercise and realism.

Ultradistance running is an example alright, but of what? There is a distinction to be made between health and ultradistance fitness, and I found Dr. Craig Lewis' attempt to equate the two unconvincing ("Setting an Exercise Example," Guest Editorial, Sept. 15, 2005, p. 12).

Evidence is an interpretation of data, and interpretations are often idiosyncratic. Still, the "evidence" suggests to me that therapeutic exercise on a daily basis is a necessary adaptation to modern life. Resistance training (weights, machines, etc.), aerobic exercise, balance, and flexibility are likely components of therapeutic exercise, and an hour a day seems about right.

Play and work aren't therapeutic exercise, necessarily. They are more likely the activities of life that therapeutic exercise facilitates.

I'd rather see physicians set examples that are realistic, evidence based, and not so discouraging to the average person.
