I feel like our current generation's going to bubble in the game of longevity. Imo at the most we're about 3 generations away from some sort of anti aging breakthrough or just being able to routinely grow and replace worn out organs. If we used a few years worth of the Pentagon budget on the health related r&d we'd be set.
Anywho, I'm guessing bed bugs but far from sure. some people I know run an apartment complex in Vegas and they have to call the exterminator now n then. The exterminator says every hotel in Vegas has had bed bugs many times. They're fairly common in hotels.
