The first dozen Parkinson's patients to have holes drilled in their skulls for a novel gene therapy attempt weren't harmed-and hints at some improvement have researchers embarking on a larger study to see if the treatment really may work.Doctors reported initial results of the closely watched experiment at a neurology meeting,but cautioned that it's far too soon to raise hopes. It helps using a nerve grwoth factor to try to resuce dying brain cells.Some 1.5 million Americans have Parkinson's, a disease that gradually destroys brain cells that produce dopamine, a chemical crucial for the cellular signaling that controls muscle movement. Too little dopamine causes increasingly severe tremors and periodically stiff or frozen limbs.
A man usually needs about two or three minutes of stimulation to have an orgasm,a woman generally needs 10 times more. For a man,an orgasm is instinctive.For a woman,it happens only after direct stimulation of the clitoris. A man's climax usually lasts for 10-13 seconds.For a woman,it lasts 6-60 seconds. A man must recuperate after an orgasm but a woman can have repeated orgasms within minutes or in rapid succession. Wonder why a man rolls over and sleeps after? During sex,his body releases oxytocin,a hormone that induces drowsiness.A woman is more relaxed after sex,which is why she wants to talk or cuddle.
