I would say we're always interested in knowing about ways to prevent illness and injury. That's one of the things we pay particular attention to, because we know that preventing illness or injury in the first place favours long-term health. The challenge, though, is that some of these things are difficult to prevent. Given the nature of the work, there really are limited opportunities to modify how people do parachuting, for example, in order to protect somebody's knees.
The same thing happens with other illnesses and injuries as well, but when we find something of importance that we can intervene on, we are certainly very interested in that.
