On Jan. 2, Scotland resident Jessie Gallan reportedly celebrated her 109th birthday.

Her reason for living so long?
"My secret to a long life has been staying away from men," Gallan told the Daily Mail. "They're just more trouble than they're worth."
"I also made sure that I got plenty of exercise, eat a nice warm bowl of porridge every morning, and have never gotten married," she continued.

So basically, the key to living a long, healthy, and happy life is to avoid men forever and never get married.

Thanks for the invaluable advice, Jessie. Happy birthday!
