Future SF? with questions, please.

[STERVO]

Dear Sirs:
I am 29 year old seriously considering enlisting this winter; my goal is SF. Have purchased/read "Get Selected" and have had ongoing conversation with SF recruiter. Am currently in training. Also I have put much thought and prayer into this. It's all I think about.
Am writing to ask you guys what you think about someone entering the program at my age... is 29 too old? Will it put me at a great disadvantage? Please be frank. I was told this was the place to find out answers re: SF. Anything you can tell me regarding this issue will be helpful.

I am hoping that if I have other questions I could ask them here.

Most Respectfully,
Stervo
