Those videos are pretty good.
I especially liked the one where he went without food for 24 hours, checked his blood glucose levels before and after a cup of spruce tea, and showed what it would do for those levels in an emergency.
The production values are a little lackluster, but he's doing it all himself most of the time, and it works well.
I noticed he has two new videos up (since the last time I visited his site). Thanks for the reminder!
