If I recall correctly that video is based on an answer that /u/Iphikrates gave in this thread. Iphikrates worked together wit Invicta to create that video. Be sure to check out the Q&A video that they also did together. Check out some of his top posts because there is a ton of interesting stuff you can learn from Dr. Konijnendijk.

Apologies for the spelling mistake. Submitted this on my phone and didn't realize it autocorrected "martial" to "Marcia" until now.
