Time to test your smarts -- about sleep, sun, food, and alcohol. Just read the following questions, pick an option and then scroll down to determine if you really know what's best for your health.
- Is it healthier to sleep an extra hour or force yourself out of bed in the morning to exercise?
- Is it healthier to spend 15 minutes in the sun without sunscreen or two hours in the sun wearing SPF 30?
- Is it better to have a second glass of wine at dinner or a sinful dessert?
