The article talks about sex in the older people. For many people, when you are old, sex is something that is not suppose to be thinked. The body turns ugly, menopause blows your sexual desire away and sex gets out of your life. In many cases, this can happen but not all. Even, "people over 60 are now the fastest-growing group contracting sexually transmitted diseases, according to government agency figures. Since 2002, syphilis has tripled in the over-65s in the UK, and HIV is up by 60%. Even allowing for the fact that we're starting from a low base, this is clearly not post-menopausal purdah."

When you get older, the sex that you have is quite different that the sex that you had in the 20s. But it doesen't have to be worst. You can worry for another things, enjoy something that you probably don't even realize when you were young. Being old is not an obstacle to have sex. Sex could be the greater of your life, even if you are old, because you are not thinking about your body or if you are good enough to your partner..You just enjoy!
