Here's something more for a very cautious person to worry about:
Specific personality traits might boost the risk for Parkinson's disease, British researchers report. A more cautious, risk-averse approach to life may be linked to increased odds for the motor neuron disease, says a team reporting in the February issue of the Journal of Neurology, Neurosurgery and Psychiatry. 'This study raises the possibility that there is a neurobiological link between low sensation-seeking traits which might underlie the parkinsonism personality,' the researchers wrote. And because more reserved types are less likely to smoke, the finding could throw water on the notion that smoking somehow protects against Parkinson's disease, the researchers added.And there I always thought my risk averse behavior was increasing my chances of a long, healthy life. Bummer.
