Stabilize your age...or else
The American Airlines in-flight magazine has a warning about Deep Vein Thrombosis. Among the risk factors for DVT, it lists "increasing age."
My age increases at a rate of one hour per hour. I understand that's about average. I suppose that since people in my situation have a 100% mortality rate, I shouldn't be too surprised that it's considered a hazard.

Good Catch by Harry:
Yes, beyond a certain point "increasing age" is an unhappy condition. That same warning in the AA flight magazine cracked me up on a trip home yesterday so much that I ripped the page out of the magazine and brought it home.
