Although jewellery and underwear may seem like trivial issues, Wurz recounted a conversation with former driver Kris Nissen as proof to the contrary - the Dane involved in a firey sportscar crash at Fuji in 1988.
"He showed his body and said 'look at this'," said Wurz.
"For him the absolute most painful thing after the fire, and it wasn't a long fire, was the rubber [elastic] in his normal pants being burnt into the skin. He said [it was] for years agony and pain, and it educated me.
"At this moment I said I don't want to live these consequences, only for [not] taking my pants off and putting fireproof underpants on. The same with jewellery."
