1. the whole nature is based on preying on the weak, and that's mandatory for survival; right now some animal "kid" is being eaten alive by some predator without "empathy" of any kind
2. at this very moment some person that might be relatable to you in some special way (like a perfect fit for a friend or partner) is having a really bad day, like dying-bad
3. the amount of sophistication in cheating each other might be one of the main factors in developing many forms of language, behavior or even science
4. health statistics aren't about others; they are all about me and you, we all are going to end up in one category or the other; often we have no say in it as our destruction is already programmed inside us
5. whatever you worked on hard all your life can be gone from one moment to another; earthquake, volcanic eruption, storm or even divorce can strike any time
6. even if you dedicate your life to something amazing, become rich, respected, adored or die a heroic death before you turn a villain, at best you will be a short, quite pointless remark in the history notes; however most likely you will be as important as a dust speck
7. excitement of novelty wears off quickly if you become a hedonist; going ascetic to lowest lows so that you can reach highest highs again will become pointless at some point as well and nothing will move you anymore
8. even if you believe in afterlife, vast majority of religions will tell you that almost everyone ends up in some sort of hell or won't make it to the "next stage of game"
