Slow Aging
If I had been born with a genetic "defect" that caused me to age extremely slowly, so that I only aged 1 day from the time that Cheops built the Great Pyramid (2560 BC) until today, how much would I have aged by now if I had been born at the time the dinosaurs went extinct. (Of course I could'nt have because there were no humans, but let's just assume that I was.)

Answer: Almost 39 years.

Calculation: Cheops built the great pyramid in 2560 BC, which is 2560 + 2011 = 4571 years ago. The dinosaurs went extinct 65 million years ago. Dividing 4571 into 65 million yields 14220 days that I have aged. Dividing by 365.25 yields 38.93.
