What could you try for the first time?
I’ve always wanted to try skydiving. That’s the first thing that comes to mind for something I would want to try for the first time. The sensation of air rushing passed you as your hurtle towards the ground. Watching videos of people doing this and similar activities I always wonder if they are feeling like they are both moving slow and incredibly fast. Those videos always make it seem like the ground below them is approaching slowly, but the sound and feel of the air rushing must make it seem confusing.
Some of my friends would vehemently disagree with the idea going so far as to say “why jump out of a perfectly good airplane?” For the thrill and excitement, duh!
