Who says you can't get busy as you get old?

A new study out of Australia finds that age is no obstacle when it comes to sex--because men in their 70s, 80s and even 90s are still doing it.

And many of them even say they still consider sex an important part of life.

Researchers asked 2,783 Australian men between the ages of 75 and 95 about their sex lives, and found that 49 percent overall considered it to be at least “somewhat important.”

And nearly a third overall had sex at least once within the previous year.

Naturally, the researchers found that the youngest of the old--those in the 75-79 age group--were most active, with 40 percent of them still having sex. But even the oldest were doing it: Eleven percent of those between 90 and 95 reported at least one sexual encounter over the previous year.

And of the men who were still having sex, 43 percent said they wanted more.

Here's your odd stat of the day: Four of the seniors (0.5 percent) said they were having too much sex.

Rough life, right?

The study also confirmed the link between testosterone and sex drive, because the researchers found that the men who did it most also had the highest levels of manly hormones.

Call it one more reason to get your own testosterone levels checked--and boosted if needed--no matter how old you are.

And while this study looked at Australian men, other studies have found similar numbers here in the United States. A 2007 study found that more than half of all men between the ages of 65 and 74 were still having sex--as were 26 percent of men between 74 and 85 years old.

Another study funded by the makers of Trojan condoms found that up to 30 percent of men in their 80s were using their beds for more than just sleep.

The researchers behind the new study say that while many men were slowed by injuries, physical limitations in themselves or their spouse or the lack of a partner, others were slowed by their own doctors.

Too many physicians just assume older men aren't doing it anymore--and prescribe drugs with sexual side effects without even warning them.

The researchers say docs should talk more about sex with their older patients, but don't be afraid to take matters into your own hands here and initiate the conversation yourself.

Just don't ask about Viagra--ask instead about the natural alternatives to your current meds that will treat your condition without putting a stop to your sex life.
