The Things Nobody Explains.

Your phone rings and something tightens in your chest, so you check the screen and wonder who died, and thirty seconds later you text back saying you missed the call, which isn't quite true because you watched it happen and chose not to pick up.

This episode looks at how the most exciting sound in the house turned into a small jolt of dread, why ringing someone now seems to require an appointment first, and what a voice carries that a message never can. It also looks at an experiment where people were asked to reconnect with an old friend, almost all of them chose to text rather than call, and almost all of them turned out to be wrong about which one would feel better.

Four things you can do about it at the end, including one you could do this week.

You read the message twice before sending it. You replay the conversation for three days. You get to the party and immediately wonder if you're dressed wrong. Almost everyone does it, and most people assume they're the only one.

In this episode: what happened when researchers sent students into a room wearing a deeply embarrassing t-shirt, why being left out of a pointless computer game registers in the brain like being hurt, and the quiet reason two people can walk away from a good conversation each convinced the other one liked them less.

The summer you were ten felt like it lasted forever. Last year went by in about four weeks. Somewhere between the two, time started moving faster, and nobody ever explained why.

In this episode, we look at why the years seem to collapse as we age: the old theory that almost everyone repeats and why it probably isn't the whole answer, what actually happens to your memory when every week resembles the last, and why frightening moments feel so much longer than they are.

Four simple things you can do to slow it down, at the end of the episode.
