Age 45: You're still persisting, but there are new friends joining you, and some are leaving. Their initial passion has been numbed by the harsh reality, and they even feel despair. It's only when you embark on this journey that you can understand the harshness it entails. When you witness the might of all tribes, you understand the desperate situation the human race is in, akin to living in hell.
But you're still persisting...
Age 55: You were defeated and killed in a conflict with the foreign tribes. On the verge of death, your life flashes before your eyes: regret, indignation, joy, loss, disappointment, all transformed into a hint of resignation and liberation.
After all, your life has been too burdensome. You have borne too much, and have walked a road that seemingly has no end. The moment you die, you are finally freed, no longer bearing these burdens.
At this moment, the most joyous and jubilant smile since you left the tribe emerges on your face.
[End of this life.]
