why do people?

This can be for different kinds of reasons but all comes down to a simple equation : what you eat- what gets burned. Some people are a lot physically active, so they burned a lot of the calories they eat while exercising. Some have a really fast metabolism in general, so same thing again : they burn a lot of calories. So in order to not get big, you have to spend most of the calories you take in. If you do, you don't get big but if you don't, then you'll get since you're with a calories surplus.

its a different mindset. They burn it up in their heads. They are usually 'worry warts' or geniuses or aquarius or all three.

Its a very unique animal, able to slip by every programming thrown at it.

There is a deeper world than this....

They have a fast metabolism... they exercise.... they eat the right foods... Don't worry if they are young, it will catch up to them. Maybe they are on meth?

They aren't done growing yet,when they grow older it will catch up to them. That's why you see a lot of overweight senors these days. LOL

Because they're lucky!

their metabolism.

I do that!I don't know why.
