The great powers of regeneration shown by freshwater planarians, capable of regenerating a complete organism from any tiny body fragment, have attracted the interest of scientists throughout history.

In 1814, Dalyell finished that planarians could almost be called eternal under the edge of the knife .

Equally impressive is the developmental plasticity of these platy helminthes, including continuous growth and fission (asexual reproduction) in well-fed organisms, and shrinkage (degrowth) during prolonged starvation.

The source of their morphological plasticity and regenerative capability is a stable population of tot potent stem cells - endoblasts ; this is the only cell type in the adult that has mitotic activity and differentiates into all cell types.

Strong Sex Drive

What happens if your car does not have any gas? It stops working right? It needs fuel to function. The same is true with our libido... we needs nutrients to enjoy vibrant health and an active sex life.

If we do not put away adequate amounts of nutrients, our bodies will not be able to function correctly in general.

Vitamins and minerals are essential to every organ and process in the body. They are the building block of life, without them our cells would not purpose properly, and thus our organs would suffer and finally we would no longer be able to survive... not to mention our dead, soulless sex life.

The Goal of Sex

The instinctive natural goal of sex is procreation. Male ejaculation is necessary for this. So we naturally strive to ejaculate. Nature has a plan. So she made it feel so good that we would always want to.

However, the act and goal of sex (intercourse) in civilized man is not always (or even usually) breeding. It is pleasure. And, connection. Love. Taoist sex teaches us how to have more of this. Much more!

After ejaculation, the male body wants to rest. And it needs to rest to rejuvenate and create more semen. The fact is, within the male body, particular specific hormones are concealed after ejaculation which in fact causes a man to want to sleep.

Ejaculation is a drain on the whole male physiology. Same as a workout in the gym.

Women get just the opposite reaction. After sex, their hormonal secretions in fact energize them!

The reason this is supposed to be so is: breeding in early human times. There weren't that many of us around. Nature did all possible to get the females pregnant and reproduce.

Nature wanted to be sure those female eggs were fertilized. The man was invented to sleep after sex so the woman could run off to find an additional lover, or rather, manure for her egg(s).

Woody Allen once said about orgasms, "My worst one was right on the money." Though you may not get to bed the likes of Julia Roberts and Mira Sorvino--as the Woodman does in his movies--it's safe to say that most guys are pretty happy with the way sex feels. And yet, if we told you there are ways to make it feel significantly better, wouldn't you want to know about them? We thought you would.
