If your heart is healthy it will be able to work for a very long time.
It is up to you to keep your heart healthy.
Your heart will like it if you:
Exercise every day
You need to exercise your heart by making it work harder for at least 30 minutes a day.
Eat a healthy diet.
Too much fatty food will block up the arteries with fat and your heart will have to work harder and harder just to do its regular job of pumping blood round your body.
Drink lots of water every day rather than fizzy drinks.
Make good choices as you grow older.
You can choose not to smoke, not to take illegal drugs and not to drink too much alcohol.
You can choose to eat healthy food and keep doing regular exercise
