I respect your decision, but I think you'll starve to death. No offense, but I think the market for saggy old chicks, no matter how amazing their attitude is, is pretty limited. The reason you probably see a bunch of old farts now is because they're married to saggy 60-year old wives!
Having said that, there's an old gal named Dot in Hamilton who advertises on BP all the time. From the one picture I saw, she is just nasty, but someone must be seeing her. I think her rate is $50/hr!
