I'm thinking that it is a drone with camera. As for the water, see him sitting on top of that cliff looking down, thinking, "I'm thirsty and the water is way down there! Crap!"
To me and DF, it is more difficult to climb down than to climb up. The sight of footing is diminished, less sure, and you've gotta look down and face the heights.
I have a problem with heights that has increased the last couple of years. I need to do a hike on the side of a cliff, incrementally Behavior modification..ing my emotional response. My lack of use of muscles and strengths and stretch, with age, has given me missing confidence. Where I used to do things naturally, I have limitations. I don't think that this is age, as much as disuse over time. For example, I found my gravity inversion boots, pulled myself up on the hanging steel bar, hooked and let myself down. I needed help to get back up, last year. I'm praying for youthful elasticity, stretching, massaging and exercising more. There has been great results in my health, especially from diet, but more needs to be done. Use it or lose it. Barefoot and nudity allows the body to exercise in subtle ways that we are not aware of.
This "age" thing is over rated. The 85 year old Tarahumara man who runs to town 25 miles and more, was mentioned in "Born to Run" by Christopher MacDougall. How can he do that? Because nobody ever told him that he couldn't. Belief changes biology in miraculous ways, belief with practicality, use and awareness sustains youthful fitness. I never cared about risking life and limb like that, but some greater nude canyoneering abilities would be handy, and sustaining, and add to my fun. I never thought that I could feel and look as I do at 63, and I know that there is much more to be had. The more that I do for myself, the better my abilities and experience. My belief has had a dramatic impact.
Now, my perception of 90 is still something limiting. It is a target, a belief, and it is 30 years away. Just because my relatives get there and suffer age and health, doesn't mean that I have to. Being mostly retired, at least with more time for myself, it is time to focus less on my intellectual pursuits that I love and find as habits. There is time to find physical things to do. There is no sense to have a younger body and not use it. I need new habits, the time is there. If I'm focused in the moment, ninety will sneak up on me and I won't even realize it, just like 63 has done. All I need to know is what I feel like, what I'm doing right now. The Who, "Hope I die before get old" in "My Generation" has given me thought since back them. One must choose lifestyle wisely. There is no sense in getting old, if I'm getting younger in the present moment.
Rant for the day. Now it is time to get off me arse,
