'Life is a mountain.' This is one of the great metaphors we live by. You struggle to go up, you eventually reach the peak and it’s all downhill from there. It was in this mindset that my wife and I decided to celebrate 10 years of marriage: by climbing the highest point in Africa. Landscapes kept changing, as did feelings and expectations. At 13,000 ft, there was no more jungle. At 15,000 the terrain was lunar; the most alien-like place I have ever seen. The air was thin, it was dark and cold and it felt like we were walking in slow motion. When we reached the summit we were euphoric but with no energy to show it. Kili, as I imagine other mountains do, shows you just how estranged from our true nature we have drifted. It reinforces strengths, it breaks boundaries and it marks you for life.
