She will turn 50 in a few months, but actress Sridevi can still give several younger Bollywood beauties a run for their money with her glowing looks and svelte figure. However, she says it is difficult to maintain a size zero figure in real life.

Sridevi, who made her comeback last year with Gauri Shinde's debut directorial venture "English Vinglish", believes zero figure is good only for certain professions.

"Zero figure is good for certain things like fashion, catwalk and all but in real life it is very difficult to maintain zero figure," Sridevi said here Friday at the launch of Dr. Sarita Davara's book "Live Well Diet".

"Whoever maintains it, hats-off to them," she added.

Actress Kareena Kapoor became popular for flaunting size zero a while ago, but she is back to her curvaceous self now.

For a healthy life funda, Sridevi said: "First of all, you should lead a very systematic life to be healthy, to look good and to feel more energetic."
