Back in the old days, it was thought that as we went through life we lost neurons day by day, but research studies have refuted that. In fact, there's widespread conservation of brain cells as we age -- neurons do not die out with normal aging. They actually undergo more subtle changes.
If anything, as we get older, the development of new cells continues in parts of the brain, including the memory centers of the brain. But the way that the neurons communicate, both electrically and chemically, changes. You may see a decreased number of synapses, or connections, between cells. You may see changes in the neurotransmitters systems, the chemicals that communicate between cells. You may also see the signaling pathway within the neuron changing, so pathways that used to promote neural outgrowth and learning may be disabled, while the actual survival pathways may stay intact. -

Using a silicone-based lubricant can bring the fun back to the bedroom! It’s much slicker and lasts longer than petroleum-based lubricants. Test it out by rubbing it between your fingers -- if it doesn’t melt into your skin, then that’s the kind you want!

The results of the large National Social Life, Health, and Aging Project, published in The Journal of Gerontology, suggest that getting older doesn't have to mean saying goodbye to sex: Researchers found that 84 percent of men and 62 percent of women between the ages of 57 and 64 reported having had sex within the past year. Even between ages 75 and 85, 38 percent of men and 17 percent of women were still getting some action. The implication: You can still enjoy a satisfying sex life well into your golden years. -

A steady diet of cheeseburgers, soda, and channel surfing may seem like no big deal when you're younger, but as we age, these poor choices begin to take their toll on our health. The result? Clogged arteries, obesity, and a higher risk of problems like high cholesterol, high blood pressure, heart disease, and diabetes -- all of which can impair blood can impair blood flow to the genitals. (Diabetes can also damage nerves in the pelvis.) When there is an increase in body fat, there is also an increased conversion of testosterone to estrogen. All of these things can make it difficult for a man to achieve and maintain erections.
