Exercise? I think not.
Researchers at the Salk Institute report they have found two drugs that do wonders for the athletic endurance of couch potato mice. One drug, known as Aicar, increased the mice’s endurance on a treadmill by 44 percent after just four weeks of treatment.
A second drug, GW1516, supercharged the mice to a 75 percent increase in endurance, but had to be combined with exercise to have any effect.
I'm for the first drug, but since the second requires exercise, I'll let the mice keep using it.
