Basically, subflooring is a platform for plywood and then carpet or a platform for hardwood flooring. You could live temporarily on the subflooring, but it will be a bit weaker from it. I assume it is 1 x 6" lumber.
That is typical subflooring. Put something atop it as soon as you can afford it and have the time to do it. To use a cordless drill and drive screws into plywood atop the subflooring would be very easy.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
