No matter what age you are 60# is still a lot for a traditional bow. I'd like to comment on the draw length question. Traditional (longbow and recurve) bows are not limited to a certain draw length such as 28". The draw length they list is rated at 28". You can draw one shorter or longer, but the draw weight will be 2-3# less or more perinch, depending on which way you are varying from the rated 28". Keep in mind that usually a longer bow will shoot (cast) an arrow faster for a given draw weight and will not stack up as quickly in reaching a certain draw weight.
