I am a man of 28 disabled since birth.
I live like a hermit for over 10 years.
I survive thanks to financial support from my country since I left the family cocoon.
I have never accepted my handicap. (Femoral agenesia)
And today I realized that there are surgical treatments that could be beneficial for me physically and psychologically.
I want to read about these surgical treatments, but all the books that I find are not free.
Do you know which site would house these works 'free'?
