Be very careful about this guy…picks apart very stupid things. He must have a license for plumbing,electrical,framing,engineering, shock jock type of show. Some he is right about but most is to get …omg out of people! Don’t know but there is sooo much more that comes into play. Be careful about what you might believe. A lot is acceptable what he picks apart. If people don’t want to spend money to do it absolutely perfect that’s great. But a lot is safe the way things are done! God makes 93% of humans with a 1/4” difference in leg length. If god can’t get it right then . Maybe this guy is gods god?
