It's a tough concept to keep in mind. After all, we've been at a bunch of services in years past so you might say that you have a "good track record."
Still, there were holidays well before I was born that I didn't attend so it shouldn't be that much of a stretch.
Yet, for me, it is.
So, this year, I went in thinking to myself, "what if this is really the last Rosh Hashana or Yom Kippur that I ever experience?"
I looked around the room, watched some of the people, listened just a bit more closely to the words of the Torah and the songs.
Ever since Thanksgiving, I've been using an app called We Croak. Thanks to my brother, Barak, for pointing it out.
As the site says, "The WeCroak app is inspired by a Bhutanese folk saying: to be a happy person, one must contemplate death five times daily."
