A few days ago, while in shul, I asked my friend if he wanted to meet me for bowling at 5 P.M. He said, "I can't because I have yahrtzeit."
It sounded like a serious sickness, like "I have a cold", but worse. I asked a rabbi about yahrtzeit, and he told me that everyone that has yahrtzeit had some family member that died.
Not only that, but the rabbi explained that people even know in advance when they will get yahrtzeit, because they say things like "I will have yahrtzeit next week."
This sounds like a very serious sickness; almost like a pandemic disease! And, no one is doing anything to stop this sickness. Is there no cure or some cure being developed?
