Especially the surface of the open ocean. There's little out there compared to near land. And even if you happened to pop near a shark feeding frenzy, for 30 seconds hold your breath, let yourself sink if that happens, and just don't move at all.

As written it's just five years 365 times. The odds are very good for survival. To make it more questionable, have the owed time be five years total in your life of 30 seconds accumulated. Still the same factors apply, 30 seconds isn't a life risk. Add in the choice of extending any of these to longer than 30 seconds before the pop to use up the time. Now survival becomes questionable if you gamble too much or at the wrong time.

And most creatures are near shore or too deep to matter.

I mean, it would be extremely possible to be exceedingly uncomfortable to dangerous.

You could end up in the middle of a group of jellyfish, on a shoreline with heavy waves crashing you against rocks, in glacial Antarctic waters, on top of barnacle-covered rocks cutting your feet, in front of a ship barreling down upon you, in an oil spill... the entire premise is that it's random. Many teleports would be safe, but any might not be.

There are so many ways you can die in less than 30s in the ocean. And that's just on the surface. The offer is "into the ocean".

Nods. Don’t forget you get 50 skip days. 50. I’d burn a couple of those if I was in the middle of something at end up with like 47 left.

I like swimming in the middle of nowhere. 30 seconds wouldn’t be enough for the absolute tranquility…I mean…if you weren’t in the middle of a storm, which would be also fine for 30 seconds.
