Over time, your pearly whites can start looking a bit dingy.

What’s best for you depends on several things, including the type of discoloration and the amount of time and money you’re willing to spend.

If you are having a heart attack, chewing a full-strength aspirin tablet can be a lifesaving move. If you have heart disease, have had a heart attack or stroke, or are at very high risk for having one, taking a low-dose aspirin every day is part of a proven strategy for preventing one of these life-changers. Aspirin makes blood platelets less “sticky.” This limits the formation of clots in the bloodstream, which can trigger heart attacks and strokes. But what if you are relatively healthy? Will taking aspirin help you keep heart attack, stroke, and other forms of cardiovascular disease at bay?

Strength training is the most effective way to slow and possibly reverse much of this decline.
