Something that cannot be stopped, altered or denied in any way.

Something that is fact, nay fiction, and will occur at some point through time no matter what actions are taken to prevent it.

Spend your entire life working so you can one day lose it all. It is inevitable, you will slowly fade out of consciousness with every memory leaving your mind. Just knowing that you'll never remember your friends and family hits you really hard. Imagine keeping a well-paying job, kids, a wife, and losing it all in an instant. You end up asking yourself, "what's the point" if every single path leads to the same fate. death, death is inevitable
