Marathon mice, enhancement and the will to work out

In his article in the Pacific Standard last week, author Bruce Grierson discusses the emerging scientific evidence that the ‘will to work out’ might be genetically determined. Grierson describes a ‘marathon mouse’, the descendant of a long line of mice bred for their love of exercise, and a 94-year-old woman called Olga, who is an athletic anomaly. Both the mouse and Olga love to work out. The mouse goes straight to his wheel when he wakes up, running kilometers at a time and Olga – a track and field amateur – still competes in 11 different events. Grierson suggests that cracking the code for intrinsic motivation to exercise would lead to the possibility of synthesizing its biochemical signature: ‘Why not a pill that would make us want to work out?’, he asks.
