• Don't bother with vitamin supplements. If you enjoy normal health and are not sensitive to healthy foods, you probably don't need them and there is no real evidence that they do any good.
• Walk every day. The aim should be to do around 10,000 steps which equates to around 60-90 minutes of walking. Using a pedometer on a belt is a good way to monitor this. On the way to or from work, shops, or meetings, leave the car or public transport a bit short of your destination. In the office, use stairs rather than the lift .
