Gray hair, crow's feet, age spots. We all know the visual signs of aging, but what really matters is how your body is aging on the inside.
Here's the problem..if you are aging too fast on the inside, you could develop a life threatening illness that will make those age spots seem really unimportant.
Doctors say while we see what's on the outside, there are some warning signs to look for about what's really going on on the inside. For instance, graying skin could signal kidney problems and losing your sense of smell could be an early warning sign of Parkinson's disease.

Nails that bump up at the tips can indicate lung cancer because oxygen isn't getting delivered properly.
