In my late 40's I realized I don't get thirsty. I did when I was younger.

I'm also a big sweater so I dehydrate quickly.

I found that I would get dehydrated to the point where my body tissues would reduce in volume or something and my Eustachian tubes would open up. They would either pop as I breathed or actually transmit my breath sounds directly into my ear from my throat. Concerning, yes.

Soon after drinking a lot of water this would go away. I soon realized that I was lacking a sense of thirst and was really stressing my body. Now I make drinking a habit.
