The beds are tilted at 6 degrees so that the head is slightly lower than the body - so called ''gravity beds''.
This is holding the thread up a bit so a little help is required. The 'employer' in this case is the German Aerospace Centre institute of Aerospace medicine in Cologne. They are paying up to 12 people 18,000 Euros (rising to 30,000 recovery time) to do what ?
It is indeed Frenchie. The institute is offering 18,000 Euros for people to go to bed and stay there for 2 months (at the institute not at home) - these are so called gravity beds which are tilted at 6 degrees and give the impression of floating. This is done under constant medical supervision to study the loss of muscle power and body coordination which is faced by astronauts returning from long periods of weightlessness. This includes a preparatory course and medical recuperation period afterwards - altogether up to 80 days. Over to you.
Cheers cologne, I think I would get bored very quickly. The first official mascot of the Olympics was what?
