Not my age thats for damn sure...I had no idea it would get harder to stay on top like this, I have seen what 40 must be like boys and I don't like it.
The thing I'm noticing is how fast you can slip out of top condition at this age...atleast for me anyway.
I have always eaten pretty much anything I want and I can see that might be a problem real soon.
A) you have a job, so you have economical freedom that you didnt have when you were 18-25 for example
B) you are more mature so you might not do all the stupid things we all do when we are 18
C) you are still in your prime physically/sexually speaking
so a+b+c= you are the King of the World UNLESS you happen to be married in which case 90% of your energy go towards raising a family
