For most of my life I held onto a gripping fear of heights. If there was the slightest hint of an edge from which I could fall (to my certain painful death no doubt) vertigo would take over as a full surge of adrenaline brought on tears and stole my legs from under me. My rational mind tried valiantly to talk my irrational self into all the logical strategies to compensate for and minimize this fear. The result of those efforts was my rational mind considering that irrational self had some very good arguments why being so afraid was not so irrational after all. Being afraid kept me safe. I happily stayed on terra firma with feet planted, no edges in sight. Looking up at all the crazy folks who dared risk certain painful death.
