Fortunately and unfortunately, I nearly always travel with one or more young kids, which means I can't realistically do stuff like this that'll delay things (they have small bladders, little patience, and are curious). However, they usually have me go through the metal detector instead of the backscatter machine, so I tend to avoid that part of it.

Before our last trip, I read about the facial ID thing, and I was worried because my passport was expired (we were traveling domestic). Fortunately, it seems neither of the airports we went through were implementing it yet, so I'll have time to renew before it's a thing.

I just wish we can all come to our senses and realize that the TSA doesn't really make us safer and that it just makes everyone mad. Unfortunately, people just seem to put up with it.
