O2 for You You

Get moving, people! Forget about outward appearances for a minute, let's look at your insides. Aerobic exercise increases blood flow to your entire body. And, key point here, blood carries oxygen. This oxygen helps preserve your body's tissue. Your muscles are preserved better; your joints (tendons, ligaments and cartilage) are preserved better; your skin, organs and brain are preserved better. I coincidentally read the following little blurb in Women's Health magazine's January/February issue~check it out:

"Weight gain could increase your risk of Alzheimer's disease. Overweight people have an average of 4% less brain tissue than normal weight people. Obese people have 8 % less! 'A high fat diet clogs arteries so oxygen can't reach brain cells and they die' Paul Thompson, PhD, UCLA study."

Wow.
So: you move, the blood circulates, the oxygen gets delivered, the body parts are happy and fulfilled, the body parts perform optimally. You move less, this happens less.
