Sad to hear of the death of TV chef Keith Floyd - Floyd on Fish is still one of my regular go-tos for advice.
How do you communicate vision by touch? How do you explain a sound by smell? Synesthetic complications are difficult to overcome and the early TV chefs had to learn to communicate taste and smell by sight and sound. Passion, energy and occasional over-indulgence were Floyd's hall-marks. We watched others enjoy what he did and deduced that we would too.
Bit of a nutter but the world needs eccentric boundary-pushers. They are only defined as eccentric in the first place because they don't accept the limits previously imposed. RIP.
