Look at this photo. On the left is me canoeing over the gnarly double drop fall on the North Esk river yesterday and in the centre is the 10m high opening waterfall on the Falloch. Both of these I paddled without incident and came away feeling suitably smug and self important. On the way home yesterday I stopped in at the leisure pool (right image) for a relaxing swim and tried a flume for probably the first time in my adult life which made my head feel wonky and it's not felt right since. Now explain that!? This brain injury thing makes no sense whatsoever.
