It's quite simple, guys – having a bad diet and not exercising regularly are sure ways of ensuring you need to visit the doctor often when you're older.

It's also really important to make sure your hygiene skills are top notch. Make sure you wash and change your underwear on a daily basis, brush your teeth at least twice a day and always wash your hands after you have been to the toilet.

These questions will test your understanding of a good diet, why exercise is good for you, and your knowledge of personal hygiene.
