Decca Tree is a really cool mic technique that gives some very detailed imaging and great sound stage depth. I'm a bit of a geek when it comes to that sort of thing but then again, I dare say most of us here fit that category. This is a forum all about audio after all.
As for the Krill oil, this is the best one I've found. It isn't the cheapest but it works and when you suffer chronic joint and tendon pain, it is worth every cent...
