What should people do to keep themselves healthy?

They should eat healthy food, do sports, they shouldn't smoke and drink alcohol

1) My favourite activity is reading. (картинка с книгами) It makes me think a lot about characters' fates, about their relationships with others, and gives me a lot about their inner-self. Through all the books I learn how to cooperate/ socialize with people around me. 
Another favourite activity is playing piano. (картинка пианино или играющего на нем) I adore music. I hear my inner music every day I wake up till the day ends. It helps me to overcome any difficulties I face on my path of life.  
Картинки найди в интернете. Подписать их можно что-то вроде 1)the magic world of reading 2)my inner music
