Staying curious and learning new things and skills is a great way to keep your mind active. Moreover, learning new things is a lot of fun (or is that just us?), and it’s an excuse to socialize more actively with others. However, staying curious as you age is a bit of a challenge.
For one, you have lots of responsibilities in your life that leave you very little time for education. Work, parenting, etc., are your main priorities, and you don’t have much space for intellectual exploration.
Moreover, you might become set in your ways and assume that you already know everything that is worth knowing.

Fake picture. Yes, Ruby the Painting Elephant" was real, but no, that's nothing like the sort of abstract painting she created. Why someone has chosen to create this fake photo when the real thing is every bit as amazing is beyond me. mutualartDOTcom/Artist/Ruby-the-Elephant/A7030ABED6C9F3CA
Recent research shows that curiosity tends to drop off in middle age and pick back up later on in life. Older adults become more selectively curious. Specifically, older individuals show curiosity about topics that they already know and care about.
In other words, general (trait) curiosity tends to fade and decline over time, but specific (state) curiosity can rise as all the demands and pressures in life ease, allowing you to pursue more of your passions. Genuine interest in topics can lead to massive enthusiasm in learning more about them.

From a comment on Reddit: "They actually found that this hurricane hit an underwater shelf which was the more likely driver of the turn. It followed the same path as a previous hurricane. There is some speculation that the dry ice lessened the strength of the hurricane, but personally I believe that hurricanes are so massive and so powerful that humans are largely unable to do anything about them at all."

TIL about wet-bulb events - when it’s so hot and humid that your body can’t cool by sweating. A wet cloth on a thermometer bulb normally cools it more than one without a cloth. But when humidity is very high, the wet- and dry-bulb temperatures are the same. This can ultimately be a lethal event.
bazjack 10 hours ago (edited)
New England is having one of these right now. I understand that using a fan - not an AC unit, but a plain fan - is counterproductive during a wet-bulb event. Usually a fan's cooling effect comes from making the sweat on your body evaporate quicker. If the humidity is too high, though, the sweat can't evaporate, and therefore the fan is just blowing hot air at you.
#40
TIL in 2021 NFL player Alvin Kamara had yet to spend any of his salary after 4 yrs in the league despite signing a $75m contract in 2020 with the New Orleans Saints.
