Sorry, but there is no such thing. A British conductor and his wife decided to kill themselves rather than face blindness and cancer respectively. How many people do you know have become either deaf, blind, or contracted cancer. The only thing I read in this story is that they life this man has become accustomed to is crashing and rather than face the new challenge, he kills himself and somehow convinces his wife to do the same. This couple is being called brave. I don't get how choosing death over life with adversity is brave. It is like taking the chicken exit at a rollercoaster. You don't call somebody brave for walking up to the ride, rather it is brave to ride the ride.
When we call people brave for killig themselves because of a loss of quality of life, when will we start calling people brave for killing other people that weren't "brave" enough to make the decision. Perhaps we should ask some Germans circa 1930's.
