Dangerous stuff !!

Had a lovely afternoon with an old teaching  friend .We were just wandering through Covent Garden and I came across this amazing head . of a street entertainer . He was just bent over his bag  getting ready for his act so I asked him ,very nicely ,if I could blip his head , He said -of course and we had a chat about how long it took to do- only about an hour .
I saw in his bag a bed of nails as well as  some huge ,very sharp ,cleavers he used for juggling !!!!  Dangerous stuff !
 I asked if he had ever hurt himself -He obviously took his art very seriously and said he had to practise 110 %  !!!!! 
What a nice chap !
