Nope. When you pass you will miss feck all. You won't be lying in the ground lamenting the lack of anything. Or in a crematorium or its environs, either.
Reminds me of a Polish friend who sprinkled her boyfriend's ashes in the park and visited every week. One day she saw a little robin there and thought that was yer man come back. The following week there was a dog turd there. No idea what story she made up to explain that.
