I've been saying it since I began shooting - time at the range is as relaxing and beneficial as yoga. (and now I have science to back me up!)
Shooters who have never tried yoga probably don't understand how two things that seem so absolutely worlds apart could possibly have anything in common. But being aware of and following the 4 Rules, carefully loading your firearm, aligning your body in the proper stance, holding the firearm securely in your hands and being conscious of your breathing as you pull the trigger slow enough so as to be surprised each time the gun fires, if done right, is almost meditative.
The common factor? Mindfulness.
So go shooting - recoil therapy truly is good for your health.
