China is having it now so obviously nothing is changing. it's all a myth. Even causing their covid handling problems. Testers in hazmat suites getting way to hot. Other problems too in that area. Their handling has worked very well in the past but it's not now. Sounds like export shortages again so look forward to price increases.
I wonder if the 13 dead people (during heatwave) saw the advice or just plain ignored it. I'm sure if someone had thrown them a flotation device instead of a bucket of common sense, they'd still be alive today.
