Indy,
I was almost 50 yrs. old when I finally got my braces. They estimated I'd wear them for 2 years. It was 3 1/2 years before they were removed, and then I was in retainers for another year. I am just now graduated to retainers 12/7 instead of 24/7. I have the retainers for the rest of my life, or risk my teeth moving back to where they were. And I would choose to do it again. I have NO regrets. I hated my teeth most of my life. Could not afford to do anything about it. When I could, I did. I NEVER smiled with my mouth open. I do now, all the time. I did, even with the braces, as soon as my teeth started to straighten out. I did not mind the braces, or the pain, or not being able to eat certain foods. I even gave up my beloved popcorn! I would second everything Teigyr said. She gave you some awesome advice. Don't worry too much about eating while on the bike. There's always the goo/gels. They go down easily. No advice about dating, as I am married. But I can tell you that the braces were never a problem. Honestly. Just be careful, if needed.
