But do we stay smart if we stop exercising?

i.e.: What happens to your brain if you fail to keep those New Year’s resolutions?

This question was tackled by researches at McMaster University in Hamilton, Ontario and the University of Sao Paulo in Brazil. The studies were, I think, startling as always: Rats who exercised generated twice as many memory cells as inactive rats, making them perform much better than their inactive compatriots. Sounds great!

The bad news: three to six weeks of inactivity and slothfulness later, all positive memory affects of the exercise had worn off. Diligence wins again.
