What disease clues is your body giving you?

A hand is seen.

From cancer, to stroke, to Alzheimer's, clues to conditions you may be at risk for could be hiding in plain sight.

For example, redheads feel more pain. One study shows a mutation of the gene responsible for red hair may also control the way the brain regulates pain sensitivity.

If you fly off the handle, check your hands. A study in the Journal of Communications found if you have a smaller index finger than ring finger, you may be more likely to be verbally aggressive.

A 2010 study showed men whose index fingers were longer than their ring fingers were 1/3 less likely to get prostate cancer.

Height-challenged people may have an advantage. A study in the Western Journal of Medicine found the onset of chronic disease is often delayed in those who are shorter than average.

Your arm length could be a tell-tale sign of Alzheimer's. Women with arms less than 60 inches across may be 1 1/2 times more likely to develop the disease. Also, women with smaller calves could have a higher risk of stroke.

Finally, take a look at your finger and toenails. If the very base is purple or blue, it could indicate a heart or circulation issue.
