BBC Science: how to fill space

Exercise is addictive we are told in the headline. But we have to wait till the bottom of the article to read 'The researchers admitted that it was not yet clear whether the same phenomenon would hold true for humans.' Still, at least the writer of this article asked the question instead of just rehashing the press release.

Addiction is an extremely dubious concept because it implies that we are basically helpless to control our urges. While certain substances do seem to make chemical changes that make cessation more painful, e.g. nicotine, heroin, it is still the case that many people give them up every day. To suggest that exercising regularly can become a matter of habit or even obsession is one thing. To suggest that it is addictive is quite another.
