It's about as inexact as it could be. It's meaningless. It vaguely says something only about what you see. Not what's better or worse and why, unless implied, or what you'd do and why you'd do it because of what you saw. A non-argument.
The implied point- that you have to have had an easy life to naively expect living forever to be puppies and sunshine, or even merely bearable - isn't even justified, in that quoted post nor in reality. I'd want to live forever mainly because of the hardships I've known. Because I've never known any where tackling them,successfully or not, left me with a bad conscience.
It's a bogus argument like so many others made by mechanic before. My money's on the real argument being that because life is hard it's not worth living. Well ok, give it up. It's only hard because you don't have the self-respect to take adversity head on and not beat yourself over failing even though you did your best.
Like I said. Defeatism.
Yes, but eventually you have to face the "Gnab Gib".

Ha. Took me a while to figure it out.
