it depends on the overall appearance and attitude of the older person. For ex. if he's fun, exciting, physically fit, smart and has a sense of humor, then it may not make a difference.

but if the older person is apparently "old".. slow moving, not sharp, out of shape..aging quickly... then i would definitely say.. it can't possibly be a match, unless the younger person has an "old" soul too..after all age is nothing but a number.. Im 46 but EVERYONE i meet and know thinks that I'm 28..to 30..I look young and I get along with all ages,,genetics, i guess.
