Luckily I'm blessed with an extremely high metabolism!
And you are what age?
39. Yeah I know, it's slowed a smidge.
Your not even close to slow.
At 39 I could eat just about anything and not gain weight. If you are normal slow is still waiting for you. Thing is you can beat it, but it may require a little dedication.
Then again, you may never have a problem, but most do.
