MONTREAL—Age has yet to catch up with world champions Rosie Asch, 81, or 80-year-old Huguette Fontaine.

“I eat well, I sleep well and play well,” said Asch. “I’ve never smoked and for wind that’s a big key.”

The same recipe had been largely followed by her doubles partner.

“I eat good food, I never eat dessert. No sweets and there’s a lot in the genes, and no cigarettes,” said Fontaine.

What these two are able to accomplish on the world tennis stage is remarkable. They were both always just recreational players, yet they're now taking on the world's best in former tour players

“These played at Wimbledon in their 20s, earlier on in their lives. They still have great strokes, but they don’t move as well,” said Asch.

Fontaine chalked up their wins to being more mobile on the court.

Sure they're in shape, but a doubles team is more than just two good players. An attitude of support for one another is vital and these two are true best friends.

“Thirty or 35 years ago, when indoor tennis started to flourish, we were at Cote-de-Liesse, that was one of the first indoor clubs, and we started to play and we got a big kick out of it,” said Fontaine.

You may not know these world champions, but they're what we are all aspiring to: long, healthy lives filled with friendships and accomplishments.
