You may think that offering your seat to someone elderly on public transport is a considerate thing to do, but experts have revealed that doing so could actually hamper their health as they age.

In fact, old people should be encouraged to stand and discouraged from taking it easy in order to keep themselves fit, an Oxford professor claims.

Sir Muir Gray, clinical adviser to Public Health England, has spoken out to say the elderly should try to walk for ten minutes a day and relatives should encourage to take the stairs instead of a lift or excalator.
