In the song I Want It All by Queen, there are these lyrics:
I'm a man with a one track mind
So much to do in one lifetime (people do you hear me?)
Not a man for compromise and 'wheres' and 'whys' and living lies
So I'm living it all (yes I'm living it all)
And I'm giving it all (and I'm giving it all)
I can find a similar phrase "whys and wherefores", which seems very old and roughly means "reason".
In the song here, I guess it means "no excuse"? Is it natural to say with this phrase? Is there some subtleties in using it? The song is so emotional.
