LATEST: Sarah Jessica Parker blames her ageing body for her recent tendon injury.

The former SEX IN THE CITY star, who turned 40 in March (25MAR05), was left in severe pain after sprinting down a sidewalk in her trade mark stilettos.

She reveals, "There are some physical differences (now I'm older). I ran down the street the other day and I tore a tendon.

"I mean, I used to run down the street forever. And my neck and back hurt. Even my teeth hurt.

"I'm thinking, 'OK, right. I guess I can't run down the street in heels anymore.'"
