People think middle age is around the age of 50. This is when we grow 'old'. A new study says middle age starts at 60 or older. The biggest reason is we are living longer. We are healthier, eat better, exercise more and we have nicer lifestyles. Life expectancies have increased. People who are 50 are not old. They are middle aged.

Britain's National Health Service (NHS) said the study is not 100 per cent true. There are things that can make us die younger. There may be new diseases and infections. Drugs may no longer work. There are also more people with diabetes and obesity. The NHS said we should eat healthy food and exercise to live longer.
