This week, as Valentine's Day approaches, I am combining my duties as health and fitness guru with my role as agony uncle. Here is a selection of questions from my postbag:

A Actually a broken heart is potentially a great aid to wellbeing. A programme of heavy sighing can do wonders for your lung capacity and will also tone up those stomach muscles. Try to begin your day with 30 heart-rending sighs. Follow this with some heaving sobs when you have your mid-morning energy drink. Sighing and sobbing are an excellent form of exercise, as they can be done anywhere, including at your office desk. Tear ducts also benefit from regular weeping, but be sure to dispose of those soggy hankies responsibly.

Q Last Valentine's Day, my boyfriend took me out for a romantic dinner and the oysters made me vomit over his dozen red roses. How can I avoid this happening again?

A Tell him to skip the oysters and remind him of the aphrodisiac qualities of a cauliflower smoothie.

Q I am in love with the receptionist at my GP's practice. I go there frequently with minor complaints just to see her. When I ask her out on a date, she is cold, negative and unhelpful. How can I win her?

A Contact your doctor directly and ask him (or her) to make an appointment for you to see the receptionist. That's your only chance.
