Like a new born baby.

Two elderly gentlemen from a retirement centre were sitting on a bench under a tree when one turns to the other and says, “Slim, I’m 83 years old now and I’m just full of aches and pains. I know you’re about my age. How do you feel?”

Slim says, “I feel just like a newborn baby.” “Really! Like a newborn baby?”

“Yep. No hair, no teeth, and I think I just shit myself”
