We'll just start with everyone Born in 1945 and get the others as they reach 65. We'll stop when I stop seeing aged couples out for a walk in the park wearing matching grey pony-tails & dressed in matching Mountaineering outfits walking dogs with Gore-Tex booties on thier paws, and old guys dressed in top-end ski clothes parking thier fat asses in the ski lodge but never actually getting on the slope.

We can just taint the nation's Viagra & HRT meds with Sodium Cyanide. It'll save ammo & money.
