I'm turning 30. How does it feel to be old? What happens to the body? What can I do to stop aging quickly? I haven't had sex in 2 months when I used to have it every few weeks but I don't seem to care. I've heard when you get older it's harder to learn too, is that true? What are some aging myths that are untrue or interesting information on it? What are some health problems to look it for as I get older?
