Yes it's an eye opener ! been through all stuff like that 20 years ago life support machines, expensive care units, operation, operation, operation, drugs.... but that's all over and done with now and I'm the same age as you. It gives you a different outlook on life, when you're having your op and find yourself out of your body in total peace looking down at the op you won't be hanging out to get back in it lol
I hope it all goes good for you and come out of it a new man !
