Totally with ya on this one.
I can't imagine anything worse then getting to a stage in my life and not being able to fish due to a preventable health issue.
For those who think "yeah, thats fine but its too late for me", let me tell you, its never too late! The human body is an amazing thing.
p.s. How long can you hold the "L" position?
When sight fishing, look over your shoulder from time to time, you never know who's behind you
