(You're talking to two different people and that quote wasn't from me. I would not go so far as to call myself an enthusiast, but I plan to use whatever life-extending things become available. IMO, nothing that currently exists is proven enough to bother with.) I am aware that people die, and that over a longer time span more people will die. I think the real philosophical difference here might be that there are no completely irreplaceable people in my life. There are people I like very much and will be very sad when they die. But there is nobody in the "life is literally not worth living without them around" category for me, and I don't expect there ever will be. I'll grieve, and then I'll continue. It has happened before, and it will happen many more times even within a normal human lifespan. I do not expect this applies to everyone. My sense of meaning, to the extent I have one, is probably somewhat less dependent on interpersonal relationships than most people's.
