I've had a job for the past eight years whereby I travel a lot. Usually on a plane at least twice a week, but very often 4 flights a week and sometimes upto 12 flights a week. These flights often involve crossing the whole country or to NZ, but also include up and down flights, such as Melb to Syd, Adel or Hobart.
Whilst I'm no athlete, I am 196cm tall and the air, the cramping (although I'm often in Business Class), the inactivity, and in my case the early mornings and late nights, plus the free food and drinks at the Qantas Club really does take it out of you - I cant describe how exactly, but it is taxing.
Both WA teams should pool their resources and buy a plane. Maybe the Docker Fokker as the WA teams are either Dockers or Fokkers.
