Honestly, most people who die of old age die from cardiorespiratory problems. The question asks about living forever, which implies immortality. Therefore, if you “died” in some way, you would feel constant pain forever. This would be especially bad if you were in an accident that destroyed your body.
At some point, your bones will break, and your organs will stop working, so you won't be able to move or perform basic functions. You will appear dead.
In the worst case, people might bury you alive. In the best case, you will experience the worst pain anyone has ever felt due to the extensive damage to your body. Even if you have enough money, I don't know if future medicine could help you. However, if it works, and you haven't lost your mind, it might be worth it?
