What is the 'immortal snail' question and why is TikTok debating it?

TikTok has become enthralled with the "immortal snail" question. It's a hypothetical where you're presented with one part wish-fulfillment and one part disappointing caveat. The "immortal snail" scenario has circulated the internet since 2014, but it's just now made its way to TikTok. The Rooster Teeth Podcast uploaded a clip from their podcast to YouTube. In the episode segment, the hosts come up with the scenario. In the mental exercise, a person is paid $10 million and granted immortality. The kicker is that a snail that can instantly kill them follows them for the rest of their life. The video has since accrued over 3.5 million views
