I often find myself looking for the expiration date on foods. That gets me thinking...
When is MY expiration date??
Till 120 by all of us!!!!!
Someone once came to Rav Shlomo Zalman Auerbach and with a broken heart told him that he has a fatal illness and the doctors have no hope for him.
Rav Shlomo Zalman told him "How fortunate you are!! You can prepare yourself to meet Hashem by paying all of your financial debts and asking mechila from anyone you may have hurt".
[Halichos Shlomo page 44. Incidentally, he says there that a general "Are you mochel me" only works for little things but if one seriously hurts his friend he must specify].
