Life’s unfair

I feel so much for people that can’t see or hear, to have a sense so primitive taken away from you at birth, or even worse, half way through your life is terrible. I just saw a local who’s blind and train’s guide dogs out on the streets everyday and realised that not very many people appreciate that, or even know it. What else has he got in his life? How much does he get paid? And does money even serve much purpose to him other than feeding himself?
