Jack and Greg were chatting on Facebook one evening.
Jack : "Do you notice that we get weaker as we get older?"
Greg : "That's only natural, bro."
Jack : "I really look forward to the day scientists discover or invent some kind of pill that makes human being healthy forever."
Greg (laugh) : "That may never come true, bro. There are, however, secrets of becoming healthy."
Jack : "What are they?"
Greg : "Dalai Lama told a reporter who asked him that question 'eat well, sleep well'. That works for him and me."
Jack : "Sounds good to me. I think I'll do that from now on."
Greg : "Wish you well, bro."
