I love how people gave suggestions when this guy actually might do it...
"but you know I don't take the conventional method all the time."
It's a clear he's taking the mick. His life, his choice anyway.
Nearly all lives have no impact and are forgotten within a few decades of death anyway, and all lives will come to nothing in the end. No life is really special, that's just a deeply-rooted myth. The moment that humans become extinct will be the moment when all of our "footprints" will be forever destroyed and
forgotten.
Not that applies to our generation though, since we'll be
that long before then. You can see that just by asking yourself, "who was my 4x great-grandfather?" Nearly none of us will know unless we've done genealogy, and even then it will still probably need referencing to remember. They are as consigned to oblivion as we will be.
