We're all Lemmings

I always find it funny (not funny, there's a different word, I just dont know what it is. If you cant tell, I know heaps of words good and stuff. ba. ) that we as humans, injure and kill ourselves so easily, and so frequently. Now, this is definitely not a 'stop the killing' piece, by all means continue, I dont like many of the people that are dying anyway. But, you know as a kid when you played Lemmings and you watched all the different ways they died, I imagine someone (like the aliens, or more realistically, Optimus Prime) watching over Earth and just being baffled at how dumb we are. We invent cars, people crash them and die. We decide to ride horses, we fall off and die. We invent narcotics and other drugs, we use them and die. We invent skyscrapers and tall buildings, we jump off them and die. We invent aircraft, we crash them and die. We invent guns and other weapons to kill ourselves. I just find it _____ (insert correct word. not funny. but something. ok maybe funny) that we are able to find all these new ways of dying. Think about how humourus this must be to the Transformers, or whoever is watching our existence play out.
In the end, we are all just Lemmings without green hair.
