In reacent years,people keep a health and keep exercising is more and more important. After that thing happened I find I was not as storng as old grandfather.
One day,my grandfather and I go to the supermarket.When I was out of brethe walked behind him,he wemt ahead vigorously.we can see from it that ordinary spent-exercises are very benaficial for us.
This is not a good suggestion some one may spend plenty of time on the fitness.Do it suit you.
