Ok, I suck. I can’t post a link to the webinar for some reason. There are two of them by the same guy. Both are worth watching. So here’s how to see them.

Go to pera.org.
Click on the “webinars” tab.
On the first page that pops up you will see a webinar given on December 18th 2020. Watch that one first, and then watch the one from May 23rd 2021. That will help you understand what is going on better than i or anyone I know can explain it.

BTW, any of the webinars by PERA is free to anyone and you can watch any or all of them you want. You have to give your name and email address but there is a TON of FREE information in those webinars on a wide variety of topics. Well worth the time of you like to self educate.
Im gonna have to check that out also thanks for sharing!
