First, learn how to deliberately slow your heart through conscious will
The Glorious 12th, that archaic celebration that marks the start of the grouse shooting season, is upon us. Whatever we think about it, the skill itself is of interest to neuroscientists. Marksmanship depends on exquisite coordination between eye and hand, and while left- or right-handedness is well established, it is less known that you have a dominant eye, too. Test this by looking at a small, distant object. Point at it then follow your finger with your eyes. Close one, then another. You’ll discover your finger only lines up with your dominant eye.
True marksmen use biofeedback (gaining control over normally involuntary functions) to keep their hand steady, learning to deliberately slow their heart through conscious will to reduce the variability in their shooting.
