Staying fit and healthy is part of being a citizenhunter, as I have mentioned before. It's important to avoid health complications that are a drain not just on you and your family, but also on taxpayers.

Now there's another reason to stay fit, so you can live longer and do citizenhunter activities for even more time. Though it is somewhat common-sense, a new study by the University of Toronto gives scientific proof to what you may have guessed: that the aging process can be slowed by working out regularly. If we exercise daily, the study shows that we can increase our aerobic power by a quarter in terms of fitness, making us up to a decade younger! Who doesn't want that? That is about as close to a fountain of youth that one will find.

Remember that drinking and smoking are also no-no's, especially in excess.

Exercising also boosts your immune system, gives you better recovery time when you get injured. And better balance -- I mean literally, not figuratively, but that probably applies as well. Your body learns to take in more oxygen from exercising, which makes breathing easier! Now all we have to do is get our air cleaner so that that is even more fun. You can always check out my colleague Kimberly Garrison's columns and podcast for the latest fitness tips.
