What "form" do your tea-leaf predictions have? I may have a flutter.
I once had a weird premonition that Ricardo Patrese was going to die (Estoril 1992). This was pre-Senna, when "nobody" ever died at GPs any more.. but it wasn't really the sort of thing you can have a flutter on,

so I didn't put any money on it.
As it is, Ricky had a monumental shunt with Berger..

Their wheels touched as Ricky was coming into the pits and his car was somersaulted down the road.

I nearly had a heart attack .. but amazingly Ricky survived.
I never had any other permunitions since...
