Fuck no.
Sure, sometimes I think of the freedom I had in 2008-2010ish with a nice paycheck no responsibilities to speak of, and loads of spare time. But I feel that that span of time was too short to be representative of anything. Before that I was perpetually broke and after that I had to pretend to be an adult.
I was thinking the same thing, except a rock. I frequently visit ships as part of my job, and it would be no problem dumping it somewhere it would be likely to remain undisturbed for the rest of eternity. A grain if sand is likely to move with the currents. A rock will not.
