Seriously,would you date someone half your age ?

I have a couple of good friends in their lare 20s. Both beautiful athletic and smoking hot young professional . We get along great and even share a passion for trance music, and we flirt all the time. I cannot imagine dating someone their age.
To me it is a 'daughter's age' thing. I am more like the over 40 ones.
So, my simple answer is ' no'
Besides palling around with them and their friends is a total rush.
