Share the secrets of young-at-heart celebs

Penny Smith, 51, TV presenter

The secret? Keep on partying!

GMTV presenter Penny doesn't allow those early-morning starts to meddle with her social life - and insists she rarely turns down an invitation. ‘I go out at least five times a week,' she admits. ‘Sometimes I drag my carcass out of the house and think, "I don't want to go" - and that's when I have the best nights.' Penny's even adjusted her sleeping pattern to fit her busy lifestyle. ‘I sleep in two shifts - four nights at night, four after work in the morning,' she admits. ‘Otherwise I'd have no social life.' But it's not just partying that keeps Penny happy and healthy: she also does plenty of yoga and goes on hiking holidays with friends, including fellow party girl Mariella Frostrup.
