When I went to Goa with my friends this month, I got a chance to try Parasailing. I felt everyone should experience it at least once in their life.
I did not find it so thrilling or scary as I had expected it to be. Must be because of the life jacket I was wearing, the rope that was tying me to the boat, and the parachute that would break the fall in case the rope got cut. Instead, I just found it peaceful and calming. To see the world from above while feeling safe (which is not the case when I look out of the window of an airplane) was somehow soothing.
This was not in my bucket list, but I think people should have it in theirs.
