It is really mysterious, why do you call death (ergo suffering) a harmony? What are you? A glutton for punishment? Screw this so called harmony, because it has a lot of inferno.
About fun I always recall this thing: I remember two drunk 21yo guys in a train. They come out for food at Yaroslavl railway station. When they returned, one was upset, because he had a huge spot of mayo on his short. Other guy smothered him, because, he sad, they have to have fun while they still young. Rather artificial fun I have to add - booze as a doping, fun in a rush.
There is a movie I always mention too, called "Escape from Sobibor", it's abt a Nazi death camp. Some victims of "Solution of the Jewish Question" did nothing to escape, and even had fun. Some actually made the escape.
First of all: Zdarova kamrad, kak dela bratuha?

)) How are things in the Northern Capital?

I'm in the real capital over here.

Second - death and life are all part of one cycle. Just because one causes you to start running around on a piece of terrain, while the other causes you to cease doing so, doesn't mean that they're not both needed. From what I understand the actual process of dying feels good as hell, because you get a massive chemical release, apparently even the tryptamine DMT is released...
It's also appraently released at birth, and at death, so that could also be part of that conclusion that it's all much of the same.
You don't argue why your car has a forward and a reverse gear do you? I can think of death as the same sort of mechanism in terms of how it interacts with life.
And also what I mean by "snobby 105 year old" is not the fact that I'll be physically frail. Even if I'm still in peak physical condition and my brain is still fresh, you'll always be a product of a particular time.
Thus you will be stuck in your ways, the older you are the more...eventually you may kill off progress in much the same way you tried to create it.
Would you be open to new fresh ideas from some youngster who is only 200 when you're 1025 ? Let's push this theory to it's limit...and if you were born over 1000 years ago, you want to do things like "back in the day"...that's the problem there NEEDS to be fresh blood and fresh ideas. That's why other people have to die, or there won't be no progress or change in the way things are done.
Aids, cancer, and third world countries' situations are all by products of human activity, even global warming

Maybe it would have been better if everyone sat on their ass initially and did nothing. Then maybe things wouldn't have gotten fucked up to this point.

Plus you still need something to do so you might as well take emotional investment in particular issues since you gotta occupy 50-100 years of time with at least something. Someone thought hey I'd do the scientific method while I'm here...others may decide on other activities, just boredom is the engine of progress
