I wish people invented a reliable cryogenesis machine, so that I can go to sleep, come back after a century, live for 5-10years, and go back to sleep. Repeat the cycle.
I don't care about living a long life, it only burdens the body and mind. I want to see fast paced changes happening in front of my eyes. Evolution takes millions of years, technological advances takes century. Being awake for that long only makes you miserable, because of all the shit happening in life. Let's admit that life is for the most part a shitty deal, with some moments of excitement.
