I think I discovered why women live longer then men. This thought came to me while on the treadmill at the Wellness Center. I saw this couple come into the gym together and each went into their respective locker room to change. When they came out the guy went to the weight area to pump some iron. The women went over to the cardio machines and jumped on an elliptical. After a while she did a bit of lifting with her boyfriend, and they went home.
If you think about the exercise practice of males, it is generally lifting weight. On the other hand, there is constantly less females in the weight area, and generally more on the ellipticals, stationary bikes, and often the treadmills. So females are favoring the ever so important cardio rather then standing and lifting weight.
Another thing I thought about is women generally consume fewer calories compared to male counterparts. It has been shown in research on rats that a calorie restrictive diet can vastly increase the life of a the rats, and it has even been shown to occur in humans. You can read about it here at the MayoClinic website. I believe one of the main reasons a low calorie diet extends life is due to less oxidative stress from metabolism
Or it could be that guys do stuff like this:
