If it's me I can bear to losing people who important to me.
Heck, I will come afraid interacting people if I am have long lifespan because afraid losing more.
Yeah... it's demerit for long lifespan, especially if people who dear to you is having short lifespan. You will left alone while all people die earlier.
I like MC friend so much, they overprotective to her.
Of course I know it's dangerous for female go alone in train for 2 hours. But recently people too careless for thing like that before some incident happened.
