Remember this photo? It was taken on my Annapurna Circuit trekking trip.
After we settled down at a guesthouse, we took a day hike to a very high location, probably around 5000 metres.
I raised the idea of taking jumping photos. Both myself and Aaron, another young Canadian guy, did it.
But it's not easy to catch a good jumping photo! So both of us jumped a lot. Eventually we got satisfying photos. As the one you see here.
But there was a consequence! That night Aaron became sick. He got a bad headache, a typical symptom of AMS.
The reason is that, although both of us jumped a lot, Aaron is 8 years younger than me. So he's more vulnerable to AMS. I was fine though.
