people like to bring up things like "all your loved ones would die before you" as a concern re: immortality. But the real danger for me would be that i'd literally never get anything done again. I'd adopt the elvish lifestyle immediately. Not doing anything in a week that could be done in a century. Not getting anything done in a century that can be done in 10 centuries. Spending the next 100 years reading 1 book very slowly because i have infinite time and don't care.
