Hormones

Is it normal to become more hormonal as you get older? I am just wondering because it seems as though I have. I am much more sensitive lately and will pretty much tear up or cry at the drop of a hat. And if you know me well, you know that I am not a crier. I'm pretty sure my best friend could probably count on one hand the times she has seen me cry!
Maybe it's because I have a lot on my mind right now. Or maybe our hormones do change as we age. I mean I know they do, I just didn't think it would happen at 25!
