One of the community tasks in which I am involved is to serve as a member of the Ritual Burial Society, aka the Chevra Kadisha.
The ritual process of preparing the deceased for burial is fascinating in and of itself, but I find two elements of it gratifying in particular.
First, the serious dose of perspective that it provides you on the ultimate end of your (all of our) lives.
Second, the comfort in knowing that, down the road, someone will treat your remains with the same respect you show them.
