The Exercise Pill

Have any of you read this about this crazy new pill that could make people fit like marathoners? I wonder if it will make you grow an extra arm too, to help you swim faster.

Oral Pill Turns Slacker Mice into Marathonists: Study

This both sounds promising (perhaps to help people with serious metabolism problems...not slackers) and makes me suspicious (in light of potential abuse by superstar athletes).

I am glad that they have already created a test so that athletes could be checked for use of the pill. No cheating.
