I know that the meaning of walks of life is
a person's occupation or position within society.
But in some cases, I don't get it. for example, someone has been saying something about how should we live and when he was finished, another guy said: "this is a good theme in many walks of life." I searched this term on the web and found nothing but examples that didn't make any sense either; like:
My life has been forged by the many walks of life due to the fact that I have done many things but have committed to only a few. I call this venture of adventure the “many walks of life” because that is exactly what it is. Diversity Vs. Racism: A Challenge to Mankind By Johnny Ishmel Henry
Mental Walks of Life. So many steps I have proceeded to take. Never really looking back, unless an error I make. There are so many roads I could follow with pride. There is no apparent reason, for my failures to hide. "Mental Walks of Life" By Julio Toro
Can anyone help me?
