At What Age Did You Start Feeling Old? [POLL]

I've always been the young kid around the office, and I just knew that was my roll. I always joke about my co-workers being old enough to be my parents. Well, the joke is on me!

I can now admit it... I'm getting older! Even though I just turned 27, I am starting to feel old. I've got aches and pains coming from places that I never knew existed!

My husband and I started bowling on a couples league this past weekend, and I have to say I'm not as young as I once was! I knew I was out of shape, but just didn't realize the extent. The muscles in my legs are so sore today. I certainly don't feel 27-year-old... More like 67!

So I pose a question to you.

According to this article, it varies.
