Hey, DaveW -
Don't ever be sorry about being thin because those who love to eat yet need to watch their intake struggle, sacrifice and suffer and it's not very fun for them.
My husband used to be thin and ever since his motorcycle accident (when he was twenty-something), now struggles with his weight. We both love to eat and love all types of cuisine, so it's really hard for him.
So, be thankful that you are thin and CAN eat like a horse. My husband wishes every day that he could be that way again.
