Must be a full moon. Or maybe it's something to do with the date. Some very strange questions being asked about the CASA medical system.
The question as you've described it is ambiguous or you may have misunderstood it, Blumaan. The DAME meant to ask you - or maybe did ask you - whether you've been involved in any accident that may be relevant to your fitness to fly.
For example, if you fall off a ladder at your home and hit your head on the driveway and suffer concussion, that's not something of which CASA or ATSB are aware. But it is something that may be relevant to your fitness to fly.
