On the Bachelor's 13th (!) season

I was watching the Bachelor last night and found myself marveling at the age of the women on the show. Three of the four finalists are 24 or 25 years old. Yikes, that's my age! And no way would I be considering marrying a 30 something man, leaving everything behind and moving to his city, and becoming the stepmother of a 4 year old. Right now my biggest concerns are planning my housewarming party and worrying about what kind of boot to buy for New York winters. I do believe that these women are serious- yes Melissa would no doubt marry Jason. But how long could that possibly last? Do you know yourself well enough at 24 to take on the role of wife and mother? I don't. I feel like I would be swallowed up in a relationship that serious. So I have to vote for Jillian, the eldest of the group. She is the only one of the four who is still holding back from Jason and I take that as a good sign. She won't fall as quickly, and hopefully she won't fall out as quickly!
