How do you feel about touching dead bodies?

is it actually like a big deal yo touch a cadaver in a lab? I had a marine biology class that the professor brought out a human cadaver and I was the only student (class of 20) willing to assist with manipulation of the cadaver. Is it normal for most people to have am aversion to touching a preserved body in an academic setting? the first thing the teach had me do was reach down puck up his arm and try and pull a tendon to make his fingers move. It was quite facinating to see how the mechanics worked, but My peers gave a large reaction, many stepping back from me. No one else seemed even close to willing to touch or to barley look, is something wrong with me? or with my classmates? is this the right subreddit?
