Maybe it depends on the students, but based on the ones I’ve met, this couldn’t be farther from the truth. My family took a trip rafting in the Grand Canyon for 6 days in 130 degree heat. It was highly taxing on the body and you needed to be very in tune with your body during the trip to assure you didn’t get heat sickness. There were 2 people on the raft with my family serving as tour guides and experts. One was an older and very seasoned expert who knew the canyon and its history like it was their very soul. The other was a young geology student who was training to do the same. During this trip, all of us experienced the same physical challenges, but our guides were also tasked with keeping us safe and informed, setting up camp, and navigating any additional challenges that the rest of us wouldn’t be knowledgeable in. Oh and steering the fucking raft through some extremely dangerous areas that even seasoned rafters fuck up sometimes. It was a wild trip, but I’ve got a lot of props for the geologist and student that served as our guides.
