William needs to shake HIS notorious work-shy image. He's stubborn and lazy to a fault.
May I ask if you have ever saved a person from a dangerous situation? Working in SAR-services is nothing for the lazy ones: you have to be constantly able to do the necessary things in such a case, so you train and work-out and are prepared for the things you will get to see which can be quite gruesome. SAR is a job for real men and women who need compassion, energy and work ethos - and this is the job William decided upon. As I said: Nothing for the lazy ones!
