I would have liked to have swum with sharks and also done a parachute jump.
My children were going to pay for me to swim with sharks at an aquarium, not too far from here, for my 60th birthday ten years ago, but I had to have a medical certificate first. I have a problem with my left ear due to untreated ear infections as a kid, I was advised it was very unwise to do so.
I never had the opportunity to do a parachute jump in the past, I think it unwise to sign up for one now as my arthritis is getting worse.
