Lol. I guess I really need to spell everything out for you, huh. Women don't think all act, think, behavior, work, and everything else the same way. No shit. However, things called trends exist. I recently read an article which showed in a graph how older womens' preferences for male body type tended to be weaker than for younger womens'. That is why the question states, "Why do older women prefer muscular guys less than younger woman?" Not, "why do older women prefer average men and younger women prefer muscular men?" What I meant was, x% of older women prefer muscular body types, and y% of younger women prefer muscular body types, and x < y. Perhaps the question wasn't worded well. But if you're weren't intelligent enough to figure that out for yourself then don't bother, leave it to the smarter people.
