Hi Rick. This is a topic that is raised time and time again - sometimes intelligently but more often than not ignorantly and in a manner that reveals more about the individual raising it than about the respondents.
I think that age is nothing other than a chronicological representation of an individual or entity's time alive or of viability. It takes none of the key factors such as maturity, intelligence, personality, interests, etc. into consideration so has little value as a metric for relationship compatability in my view.
Responding to a couple of other specific items: a 22 year old female is surely a woman and not a girl, although of course, some women retain a childlike quality which many men admire
There is nothing wrong with that.
Are all 50 year old men fat, balding & grumpy and do they fart a lot? I may well be bald by that time but don't think the other things will apply to me when I'm 50. Besides, I'm only balding as a consequence of years of breakdancing
I personally, think we should stop generalising and being judgemental and should celebrate the fact that others find love at a time when love is so hard to find.
Just my thoughts. Best wishes to all, irrespective of their point of departure on this debate.
