How do you feel about relationships with a significant age gap?

Significant being if one partner could quite literally be the other's parent. Personally I mostly of the train of thought that says age ain't nothing but a number but at some point it does get a little creepy. I know 20 year olds dating 60 year olds and my body cringes a bit even though it's mostly none of my business. But I'm still willing to have an opinion on it. I feel like if there enough eligible bachelors in your own age group what gives? What do you gayls think? Would you date someone way outside of your age range (older or younger) and why?
