I have trouble with the quantum immortality theory because people normally die in the 75-90 years range, and it would be supremely weird for you to just keep living while those around you all died, since in our reality humans tend to have similar lifespans.

I mean, I like the idea, but it just seems so implausible.

There's no problem with the statistics. It's understood that the worlds in which anybody is 200 years old are extremely few. The probability that you'll experience such a world is either 0 or too close to make a difference. But by an anthropic principle, somebody is experiencing those worlds.
