I know everyone has opinions about this stuff so please share them.

How old is too old...

to have babies~in my opinion that depends on the parents health and ability to parent well,  as long as they're able to have the baby and care for it properly, love it,  I think age isn't important. 

to have long hair~I think that depends on the individual's face shape,  long hair does "elongate" a face and a face that has drooping going on doesn't look it's best with long hair.  I know personally.

to wear a bikini~One's never too old as long as the body is in fantastic shape.  I"ll never wear one I guess.

to go to night clubs~As long as you're of age

to wear a pony tail~hair usually thins with age, or illness so I think that's an individual thing.  I've seen older women with them,  and they look nice if they're not too high on the head. 

to wear low ride jeans~depends on one's figure I think,  if one needs depends then probably not..

to play paint ball~I was too old at 35!!  too rough a game for me!

to play with Legos~never too old,  chineese checkers are fun too played with marbles.  Not the ones from my head though.

to be considered young?~to me that's a frame of mind and spirit!  compared to trees, tortises, the earth, I'm still a baby
