Thanks mate, I appreciate you checking it out. The Facebook ones are afew yeas old but still relevant especially if you ever do any online marketing so you spend your money wisely. I was going to link them but I thought readers might not find there way back. Is there a way to link and have it open in a new window? If you are into popular science or new ideas the makers of those videos Kurzgesagt, Veritasium are TED are all goldmines .
