Is there anything wrong with the fact that my dad is having a baby at his age?

my dad is 53 and is having a baby with a gorgeous 21 year old woman. she was one of the interns at his work & i guess they started getting it on and now she's pregnant. I looked her up on myspace and frankly im a bit jealous. She resembles Kristen Bell from that Sarah Marshall movie and Veronica Mars. why would a girl that looks like that want to have with an older guy with a full beard? i didnt know that hot young blondes liked salt n pepper beards! im wondering if she used my dad for financial reasons or if she really did care for him. im not sure if they were actually dating, i know they are not a couple right now either, but i guess he did go with her to a few her gynocologist appointments since he is the father. he did mention that while he was in the room, they had with her legs in stirrups as they checked something down there. my dad just said that reminded him of the time he had a ureteoroscopy at the urologist's office last year for one of his kidney stones where they shoved an instruemnt up his ! he said he's pretty sure the whole staff at her doctor's office thought he was her dad and not the father of the baby in her! This whole thing seems wrong though, I mean, yeah congradulate him on banging a young, smoking hot blonde, but now a baby!! He had a kid at 50 with some other woman and that relationship didnt last long. For the past year he's been having some health problems like prostate problems, high blood pressure and has been ping more kidney stones. Do you think that the new baby will make him want to get his health more on track?
