Thank you so much @aceace for your suggestion. Whenever you share a video from YouTube, you can get the link and source from that video. Still, I mention the source of the video in the post below so that people do not think that's my video.
Sometimes I talk to the creator of the video what they think of sharing their video on my blog post. I got positive and encouraging responses. I made a comment on Dr Mark Phillips video and got the response quickly. Dr Mark Phillips is a criminal psychologist, high risk security consultant, martial arts and defensive skills instructor.
You can check out his YouTube channel Fight SCIENCE.
I will think about how I can give more credit to the creator of the video. Thanks again for your feedback. I appreciate that!
