Yeah, I see some kid still continue this tradition. I has take some picture of kid continue it in Thailand

I saw x-rays of such a neck a long time ago. These circles push down the ribs and shoulders, making it look like a long neck

Their bronze necklaces is indeed so heavy . It even can reach 20kg . Just imagine bringing 20kg + as their necklace every second.

From my point of view, this is an unthinkable thing. But as I already wrote, traditions are binding and it takes a long time for a new tradition to appear.
