I'm 25 and I'd date a 40 year old if he have full hair and is in good shape. 40 isn't THAT old

When I was 25, I maybe would have said the same thing.  Now I'm almost 35 and I can't get over the huge emotional &amp; mental difference between 25 and 35.  I wouldn't date a 25 year old now and definitely still would not in another 5 years. 

As long as everyone consents then it's legally fine, but I can't imagine it for myself.
