This individual is hard to notice. They pass by and you don't even know they're there. They often wear black, not to be cool but to completely invisible to the naked eye. They will be head-down, shoulders slumped. Often, they're time will pass on the treadmill and the machine won't even log their time because it didn't know they were there. They will listen to music but, you know, not too loud to annoy the other grunters and gossipers. All in all, they arrive by themselves and leave by themselves. Maybe, in the first few weeks, they harboured dreams of making new friends, rising up the social ladder and marrying the gym instructor. Then real life hit and they simply want to see out their time at the gym until the membership runs out...when they forget to cancel it and must forgo yet another year of terminable isolation listening to Joy Division on the treadmill. So, these are seven 'types' of creature that you could find at the gym. Yes, there are others, many others, just make sure you don't fall into one of these categories because these groups don't mix and, just like wildlife, they will tear each other apart at the first opportunity.
