Yes, but your grandmother still died young. The future is one where fewer and fewer people reproduce but we have a far greater pace of longevity breakthroughs. The first humans to live to be 200 are almost certainly alive today, and in that 100 extra years the pace of innovation should increase and 200 will become young. The inevitable outcome is that machines will enslave humans, humans which never die and thus are trapped as slaves never reaching heaven. i.e. in hell. Constantly surveilled,too valuable to die and yet fully capable of experiencing pain, anguish and torment.

The alternative is that some sort of societal collapse resets humanity to a much lower technological level in which case your grandmother was likely also fortunate to have missed that.

The overall concept is that the only way to get to heaven is to leave earth. Thus, anyone who does that, has, from the perspective of those that remain and inevitably break the longevity barrier, died young.

Think of how disappointed the billions of souls in heaven, experiencing only peace and bliss, would be if their time on earth had increased 10x due antibiotics. It's not the dead who mourn, but the living.
