Haha!

Says the guy who climbs on ladders all the time ;>)

I am slightly afraid of heights myself but not when there's a gate and all.
I once went for an extremely scary 10 to 15 minute walk, over an arching cliff , dozens of metres above a wild and rocky sea (in November 2016) on El Hierro, Canary islands. I should still have some GoPro footage of that. I was literally glad I survived that walk. Sometimes I tend to push myself.
