Twenty one? Hobbits aren't counted as adult till they are 33. I don't think humans should be either. Or possibly till they're eleventy one, as the fella with the drum said up the threads a bit.

I don't feel near as grown up as I did when I was 21 anyway. As Bob Dylan once more or less wrote. You know, that fella who was a big singer many years before you were born Mbo m'boy. "I was so much older then, I'm younger than that now."
