Let's help John get better

Hi guys, as you all know our crazy friend John has not been doing very well in the last 14 months. He just had a treatment in France which helped him a lot but unfortunately he had a relapse since he got back to Australia and really need more sessions of it. Since the treatment is pretty expensive ($200 each session - and he needs lots of them) he can't really afford it especially since because of his illness he can't work much. So, I was thinking that maybe we could all chip in to pay for at least some of the treatment???
