I'm Old School! (About half-way through my academic career, I realized that I could either spend weeks reading up on each latest trend -- as here, the latest dWARs or whatever they are-- or simply let them go away, until they were so obsolete, all my colleagues would scoff at any reference to them. I chose the latter!)
(Oh yes, as an aside--given the recent Covid situation, I think we're going to have to wait at least another year for me to pay off that bet with SeaDog tix!)
