A Japanese adult video actor recognized by the Guinness Book of World Records for being the oldest living porn actor alive swears that the reason he feels so young and healthy is because of his attraction to the opposite sex.

"Sex until the day you die!" That is 80 year old Shigeo Tokuda's motto. This world record holder was a virgin until he was married at the age of 29. After retiring from his day job at 70, he started buying his porn directly from his favorite adult video company, and the director there offered him a job as a porn actor. Mr. Tokuda was finally convinced to give it a shot after two years of incessant persuasion, and the rest is history. Asked why the director specifically scouted him, Mr. Tokuda replied, "Because I look like a pervert."

" A man or woman can never stop wanting sex and interacting with the opposite sex. When you lose interest in sex, that's when you age." As funny as it may seem, it isn't all about sex to him. "Even going on a date, and being excited as you try to impress the girl in front of you. That excitement is what life is all about." Looking at the big smile on his face, he's probably on to something.

But a few years ago, Mr. Shimoda got a little too excited and had a mild heart attack after taking some Viagra. He hasn't taken any since.

Big smile:
