A Large Portion, Yes
I had some dizziness issues on and off last couple of years, and only a week or so ago did I suddenly realise that I haven't experienced it in ages. I also had all that back trouble recently, even got workmates to do most lifting for me. It also has somehow just ... gone away.I had an operation 6weeks ago and after a day I was forced to stand up and get to the chair in my room.
I had forgotten how to stand up, let alone walk. Took ages before I dared standing up and I nearly fainted getting to the chair. There is so much neural information inputs and processing required to merely pick something up.
Talk to a robotics engineer who struggle to replicate what biological systems do with no conscious input and you will never take our biological system for granted
Finally I was once awesome. Oh wait actually that's not changed.
