One day they have gone from being able-bodied - running around, picking things up with one hand - to being dependent on others at times.
Of course, throughout the rehabilitation process those who have had an injury become stronger and re-gain some of their function, reducing the need for outside help before hopefully being completely independent one day.
Those who have gone through the grind of rehab, I cannot help but salute them. I have only ever known myself the way I am, the transition and acceptance is a-whole-other element to take into account.
Having played wheelchair rugby, and travelled, with people worse off than Moses, you really do get a feel for what life is like in a chair. And, it's not easy.
But, like Moses said, sport is like a support network for those with similar injuries and function. The number of times I have watched a tetraplegic pick something up off the ground and I've thought 'wow, what a good idea' are uncountable.
The way a group of similar functioning people can push each other to be better and pull finger to do more with themselves is inspiring.
It is people like Moses Parangi who I think of when I'm having an average day, being frustrated with all sorts disability-related issues. I just hope when I'm Moses' age I have the same happy go lucky attitude he does.
