I can 100% promise that death will be a regular part of life not just 1000 years, but 100,000 years from now as well. Even if we solve senescence and we get 1,000,000 times better at emergency medicine, transplants etc. There are numerous ways to almost entirely destroy the brain in fractions of a second, or in hopelessly irreversible ways, or in covert ways that are slow but only get discovered too late. And, as long as such accidents are possible, if your life is otherwise endless, then they are in fact inevitable, no matter how unlikely they appear.

There will always be some probability of dying in a given year. Let's say our futuristic society has solved aging/senescence, and is able to reduce the rate of "random death" by about 1% per year, through technology, medicine, brain-redundancy, whatever. So if you have a 1 in 1,000 chance of randomly dying this year, next year it will be about 1 in 1,010. The area under an infinite exponential decay curve is finite. In the scenario above, you have a finite probability of dying, ever. And it's not 100%, either. It could even be quite low. With the numbers above, it's about 10% chance to die, and 90% chance to never die. I know that's counter-intuitive, and it may be that maintaining 1% reduction in random death every year is impossible, but it's not a foregone conclusion that everyone must die. Of course the heat death of the universe presents a problem. That's a good problem to have.
