reading hands

When I was waiting the traffic signal to turn green, I was talked to by a man who is small and about fifty old Chinese. He said he has been in London over thirty years. He looked humble nice friendly man. He said his work is mortgage.
He said he could read hands, so I showed my hands to him. What he guess about me was exactly true. I think he might be genuine. In Japan, some people from a religious group sometimes try to catch people talking to about reading hands on roads. They usually say that our hands said we need to join their group to be happy and if we left it, we could not be happy. But I believe the man I saw today was just kind, because he did not talk about his religious or happiness. So I wish I can see him on the road again.

He guessed that I lost my health some years ago. It is true. I do not have any sick now but I know that I do not have much power as I had before.
He said that I should eat lamb meat or venison(dear meat).These meats could reinforce our immunity system, he said. He recommends me dry read currant fruits.
He said that I can put dry read currant fruits into any soup. I think I can do issue of dry read currant fruits but I see difficulty with the issue of lamb meat or venison(dear meat) . the smell of lamb is not familiar to me and I do not know how to cook them. If you know me, could you tell me?
