Your brain uses chemicals called neurotransmitters to control everything—your focus, your decisions, your ability to execute.
Every round, these chemicals are being drained in two ways.
First, you're outside in the sun for 4+ hours. Swinging a club 70-80 times. Bending over to read putts. Walking to your ball. Walking to the green.
But it gets worse…
Every putt you read, your brain is calculating slope, speed, grain, and break.
Every club you pick, it's running wind, distance, lie, and risk through a mental calculator.
70+ decisions over 4 hours. Each one draining your tank a little more.
So you're being depleted from both sides. Body AND mind.
And when those neurotransmitters get exhausted…
Your focus fades. Your decisions get foggy. Your tempo disappears.
