In one of the first studies to examine the relationship between diet and brain lesions,researchers observed that elderly people who reported higher calcium and vitamin D intake were much more likely to have greater volumes of brain lesions-regions of damage that increase risk of cognitive impairment."Our finding of a relationship between brain lesions and consumption of both calcium and vitamin D raises the question about a possible down side to high intakes of these nutrients,"Martha E Payne of Duke University,Durham,North Carolina,said.Higher intakes of calcium and vitamin D have been promoted in recent years as a way to prevent bone loss with ageing.
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.
