I watched the video and I can see that when he does the neck part it isn't like sudden or anything. I won't have it done though.

And as far as one foot being a little longer we learned from a chiropractor how to fix that and it has worked every time. If it's done in the chiropractors office that's when they block you and it is slow but sure and one foot is no longer shorter than the other. It can be like an inch or far less that it's shorter. We learned to do it at home with thicker books put in the correct place depending on which leg is a bit shorter. We learned how to check that before to see if indeed the leg was a bit shorter. It works every time.

We don't have to do it often but when we know it's "out" and then check it and do the book blocking. I especially go back in fast.

A CMTer may have more trouble with that sort of thing than the general population. Just the way it is for some of us.

By the way a person can have a stroke if they are at the hairdressers and have your hair washed when you are laying back with your neck over the sink. I do my own and always have long before I learned that.
