Your body burns 2 to 5% fewer calories with each decade after age 40. I just Googled the word metabolism, and up came over 90 million results, including advice promising to help me ignite my Skinny Gene. I have a Skinny Gene? Who knew? The truth is, there are almost as many myths about metabolism, as there are about global warming.
There’s lots of metabolism increasing “techniques”, that in the grand scheme of things are, in my opinion, ridiculous. Here’s an example: True or False: Your body burns more calories digesting ice-cold beverages and foods.
It would not be uncommon among a group of guys, for one of the men who’s been lifting weights to build his biceps, to push up his sleeves, lift and bend his arms, tighten his fists, and flex his biceps. Showing off the results of all that hard work in the gym. Too bad we can’t do the same type of thing to demonstrate the strength and size of our heart. People tend to forget that the heart is a muscle too, and it responds to exercise the same way other muscles do, by getting bigger and stronger. A well trained heart can be 30 to 40 percent…
Differences in breathing between men and women – Even when the smaller physical size of women is taken into account, their lungs are still smaller than men’s. Women also have narrower airways (breathing tubes), which means it’s harder to move air in and out of the lungs.

Without the sweeping away of debris within the cell, cells could become choked with trash and malfunction or die. In recent years, some scientists have begun to suspect that faulty autophagy mechanisms contribute to the development of a range of diseases, including diabetes, muscular dystrophy, Alzheimer’s and cancer. The slowing of autophagy as we reach middle age is also believed to play a role in aging.
Some of the most exciting scientific research of late is on the associative value of exercise and brain activity. We’ve known that there is a beneficial relationship between exercise and brainpower. But the newest findings make it clear that it’s not just a relationship; it’s THE relationship.
The best evidence comes from several new studies of lab animals. Until recently, there was little research done to isolate the one particular thing that mattered most as it related to increasing the brainpower of mice.
