A great presentation by a UK doctor David Unwin. Very mild mannered yet funny at times. Very knowledgeable with lots of data he has kept for a number of years from his own patient base. Talks about blood pressure and a bunch of other stuff.

43 minutes long but worth the time investment for anyone interested in maintaining their health.
