Would You Check?

Via Mind Hacks -- Steven Pinker says of the genes that increase the risk for Alzheimer's disease:

Still, I figured that my current burden of existential dread is just about right, so I followed Watson’s lead and asked for a line-item veto of my APOE gene information when the P.G.P. sequencer gets to it.

I would check. One reason is that I'm young enough that there's still hope for various forms of treatment or preventative measures to arise before I reach risk age. But second, if prevention isn't possible I'd just as soon kick off due to heart disease as have my soul slowly destroyed -- Camel unfiltereds here I come! -- at about age 55-60.
