Exercise...

.. was reading about exercise and its effects. Anyway, these are some of the interesting stuff that I learned. No exercise is not good for us. Guess everyone knows that.

3 groups of mice. First group was allowed a sedentary life. The second was made to 'jog' leisurely for about half an hour and the 3rd group gets marathon runner training, a 2-hour run; daily. Then all the mice were exposed to a flu virus. Guess which group had the most mice dropping dead like flies?

The group that had most survivors was of course the 2nd group. But this is where things start to get interesting. In the first group slightly more than 50% of the mice succumbed to the flu virus. In the second group an amazing 88% survived the flu onslaught. But the surprise is in the 3rd group - the die-hard exercise freaks. More than 70% kaput from the flu virus. Looks like the more and harder you exercise, the lower your immunity becomes and the more likely you are to succumb to infections or take a longer time to heal. Too much exercise apparently lowers one's immunity if this study is taken seriously.

The next surprising thing... brawn equals to not-so-smart guy; kinda like Big Moose from Archie. Gym workouts on the muscle does not seem to make you any smarter. You still have to go for those more endurance type ones, those that make you pant and puff. Cos when you do the latter, your brain gets a higher dose of oxygen and other stuff and that is supposed to help increase your cognitive abilities. How's that? LOL! But all these data are just research. There are many things which we still don't understand... I just read today that jumping up and down (despite it being on the high impact type of exercise) is good for the bones...
