At 33, Bipasha Basu is fit as a fiddle. She believes fitness is the best investment as good health leads to happiness.

"It's very important to love yourself because that's where your life begins. You have one life, one body that you need to respect and look after. There is no other place where you live but just your body," Bipasha said here Sunday at the Fittest City contest.

"It's really important that you give time to your body and care. It's the best investment you have. So every single person should teach their children to start early and start looking after your health and fitness," she added.

Bipasha was last seen in "Raaz 3", is not just a fitness freak herself, but also took a step ahead by launching a fitness DVD called "BB Love Yourself: Fit and Fabulous You". It was a 60-day routine for weight-loss.
