I was immediately very aware of every slight motion of air even in what seemed like still rooms, or generated by my motion, not even walking. It was like I had a new sensor upgrade. Almost more interesting is that it did not fade or degrade over the months that I kept that (non-)hairstyle.
The tactile sense can be a very high-bandwidth information feed.
It mostly boils down to using it as a "don't pull the trigger, the wind just did something funky" sensor.
Granted about half the time I end up throwing a baseball cap on it because not getting sunburn/skin cancer is more important to me than a few points at 600 yards, but it does help.
Opportunist...
I also found myself bumping my head a lot when working in semi-cramped spaces which I was doing a lot at the time. Hair normally acts as a small proximity sensor around your dome in a way I was completely unaware of before that.
