What are the limits to it ? Exceptions etc. Context i saw vsauces " power of suggestions " video. Is the video scripted or was the kids conditions just not real like i can understand the girls condition may be cured through placebo but come on adhd and migraines immediatly cured ?
There is a great long video on this on YouTube from Medlife Crisis who is a doctor at a London university hospital. Well worth a watch.
