My theory is that if you are afraid of heights, just don't look down. After one warmup climb at 5.7, I spent the rest of the day on 5.8 climbs. I completed one hard climb with two overhangs just because this guy remarked that he couldn't do it ... he just kept falling at the second section (He's behind Ofie in the picture below). That's a challenge in my book. Yes it was really hard .. I was hanging on for dear life using every bit of strength I had ... but I was going to do it no matter what!!!! Ofie just laughed at me!!
