Working on my feet is ok for me for now part-time 25 hours a week.
I personally would absolutely hate it full-time because of how physically exhausting it is.
I've done it for 6 years and I tell myself NEVER AGAIN!
I an doing everything NOT to work on my feet full time ever. I am studying and gaining my new qualification that will allow me to sit down while working.
I am fit and healthy. I am 43.
With age, it is not that easy working on my feet. I can feel it after ther end of 5 days week so much.
I hate the fact it gives me corns on my feet.
