A Heavenly Welcome

A contractor dies in a car accident on his 40th birthday and finds himself at the Pearly Gates. A brass band is playing, the angels are singing a beautiful hymn, there is a huge crowd cheering and shouting his name, and absolutely everyone wants to shake his hand. Just when he thinks things can't possibly get any better, Saint Peter himself runs over, apologizes for not greeting him personally at the Pearly Gates, shakes his hand, and says, "Congratulations son, we've been waiting a long time for you." Totally confused and a little embarrassed, the contractor sheepishly looks at Saint Peter and says "Saint Peter, I tried to lead a God-fearing life, I loved my family, I tried to obey the 10 Commandments, but congratulations for what? I honestly don't remember doing anything really special when I was alive.""Congratulations for what?" says Saint Peter, totally amazed at the man's modesty. "We're celebrating the fact that you lived to be 160 years old! God himself wants to see you!" The contractor is awestruck and can only look at Saint Peter with his mouth wide open. When he regains his power of speech, he looks up at Saint Peter and says "Saint Peter, I lived my life in the eternal hope that when I died I would be judged by God and be found to be worthy, but I only lived to be forty." "That's simply impossible son," says Saint Peter. "We've added up your time sheets."

Walter Fletcher

Died 7 Jun 1933 at age 59 (born 21 Jul 1873). Sir Walter Morley Fletcher was an English physiologist and administrator who began his degree studies at Trinity College, Cambridge in 1891. Upon graduation, he commenced his nearly 20-year career there, where he researched the biochemistry of muscle respiration, contraction and the role of lactic acid. Then, having gained a distinction in his field, on 1 Jul 1914, Fletcher was offered the post as the first Secretary of the Medical Research Council (originally known as the Medical Research Committee). He became an adept administrator. Fletcher emphasized funding for basic scientific research, rather than clinical research, and through his leadership for eighteen years, he established Britain as a leader in biomedical research. He also urged attention to nutritional studies for health of both humans and animals.«
