I used to swim most mornings, just a quick mile normally.
The pool opened at 6am and it was full off old people by 6:05 all meandering about leaving a trail of wee in their wake.
I asked that a lane be created at one side for faster swimmers (I’d say there were 5 or 6 of us normally) but it was refused. Then one day I was swimming along, head down. An old gimmer weaved about in front of me and I planted my hand on his head and pushed him under the water. I stopped to see where he went and he was just sat on the bottom of the pool waiting to die.
I dived down, pulled him up where he coughed up loads of water. I dragged him to the side and helped him out.
Next day they’d put up a lane rope.
