More than Half Way to Fifty

So, some of my students found out on Friday that today is my birthday. Most of them were really sweet and sang happy birthday to me. Then, boy #1 said, "How old are you going to be, Mrs. C? 26?". I said, "Yes! How did you know?". He explained that it was a lucky guess. Then, boy #2 decided to pipe in and say "Ha! You're more than half way to fifty now!". Jerk.
