People who think our short lifespans are important because they give meaning to life never seem to want to shorten their lives in order to maximize meaning.

Never dying ever is definitely a weird thing to consider, but that's not possible even theoretically. Eventually all the energy in the Universe will reach maximum entropy and nothing will be alive.

But I am very suspicious of anyone who is sure that 75 years is the optimal meaning-to-lifespan ratio.
