Heidi swims an hour a day, every day -- rain or shine. At 82, she figures she's swum three-quarters of the way around the world -- all at The Hills Swim Club, where she joined as a charter member in 1962.

"The Red Cross was offering a pin to anyone who could swim 50 miles in one year," she remembered of those early days. "My daughter was taking swim lessons and said 'Mommy, will you do this with me?'"

Since then, things have gone, well, swimmingly. Heidi's health has allowed her to do things most seniors don't get to enjoy. At 76, she tried sky diving. Twice. She still tends to her hillside garden and hosts her grandchildren for summer vacations. And she never forgets where she'd be without her morning routine.

"I'm convinced I'd be in a wheelchair," she said, referring to a lung condition she's had since childhood.

Heidi is like a fine Swiss watch. Time marches on and she keeps ticking. Oh -- and she's waterproof, too.
