A new study has revealed that a great sex life will not only help you feel and look youngeru00a0-- it will also help you live longer.

Dr Eric Braverman, an anti-ageing expert from the US, has written a new book 'Younger (Sexier) You,' in which he says that sex not only raises your hormone ­levels (so keeping you young), but can also boost your metabolism, brain function, heart health and immunity.
