history: I was really apprehensive when I went to university at the age of 30. I was scared that I wouldn't be able to connect with the younger students, and that I wouldn't be smart enough to do well. I was also unsure if it would advance my career. I was really apprehensive about going to university at the age of 30. That's okay_comma_ I'm 25 and still in college. How did it go for you?  It went pretty well! I got great grades and made friends despite the age difference.
current: That's awesome. I'm glad it worked out well for you. :)
next: Thank you! In the end I had no reason to worry about it.
