This reminds me of one of my real life heroes... a Holocaust survivor who was busy killing Nazis since age 16 as a tank pilot in the French Foreign Legion, who went on to be the 1st tank commander of the IDF [as the IDF just purchased French tanks] in the 1948 war [he literally got of the plane and was shooting Arabs within hours!] [due to his inspirational and beyond heroic life he was also made an "honorary Marine" who holds the US rank of Lt. Col just like he did in the IDF]-- After an exemplary life he, after he self diagnosed his reflexes to be not what they used to, walked to his neighbors house and sold him his [sweet] car.
I had the blessing to live in the same complex with this man, and when I started wearing a kippah he came to me immediately and invited me into his home to schmooze [I wish I could tell the stories I got to hear first hand from a real Israeli pioneer commando!]... in his eighties he is still filled with Ahavat Yisrael and makes the effort to connect with every Jew he can. He is one of the coolest people I have ever met. -- Certainly, when I am 80 or so and my reflexes start to naturally decline I will remember what the honorable type of man does in that situation.
What a tragedy the other people mentioned in this thread have ignored the inevitable signs of a long life lived.
