I ended up IN therapy as a result of this forum. "I can't help it doc, I have bikes stacked up in the garage and parts everywhere and half a dozen unfinished projects but can't help but look for more bikes!"
Roaches are tropical. They've move north with the increase in human population because our heated buildings allow them to survive the winter. So they will not outlast humans, at least in colder latitudes. So yeah, they aint so tough.
