Comedy is just to me, maybe it's a natural knack, if I can see where the joke is in the writing and I can see where the setup is and I can tell this is the way to make it.
I believe in eating smaller meals more often throughout the day to keep the metabolism going. Don't deprive yourself, just make better choices. At 50 years old it is definitely a lot harder to stay in shape then it was when I was in my 20's.
