### T.D. Lee is 80 years old

Congratulations to T.D. Lee who has celebrated 80th birthday on Friday. Betsy Devine wanted to know how could he defeat the obvious prejudice that the left must be the same as the right because the left hand is the mirror image of the right hand.

I expected to learn that T.D. Lee's left hand was longer than his right hand but the correct answer is different: T.D. Lee uses his right hand to manipulate with chopsticks but not the left hand - the Left is usually not terribly skillful - which indicates that the fermions' gauge interactions could be chiral which could also be seen in certain nuclear decays. ;-)
