Here are some little-Known Facts About Your Body:
1. For every pound of fat gained, you add SEVEN miles of new blood vessels.
New tissue needs blood supply, so your vascular system expands to accommodate it. This also means your heart must work harder to pump blood through the new network, which may reduce oxygenation and nutrient replenishment in other tissues.
Lose a pound? Your body will break down and reabsorb the unneeded blood vessels from the previous tissue.
2. Muscle tissue is three times more efficient at burning calories than fat.
This is why possessing more muscle should be a training goal for most people. More muscle = more calories burned = less fat = being more fit looking. Simple goals and simple math.
3. You are taller in the morning than in the evening.
When you crawl out of the sack in the morning you are at your tallest. On average, you are approximately one-half inch taller when you wake in the morning, thanks to excess fluid between within your spinal discs. While you are sleeping, these fluids replenish. During the day your body has to deal with the stress of standing, so the discs become compressed and the fluid seeps out. This results in you losing a small amount of extra height.
4. Your stomach manufactures a new lining every three days to avoid digesting itself.
As a part of the digestive process, your stomach secretes hydrochloric acid (HCl). HCl is a powerful corrosive compound also used to treat various metals. The HCl your stomach secretes is also powerful, but mucous lining the stomach wall keeps it within the digestive system. As a result it breaks down the food you consume, but not your own stomach.
