When I started training jujitsu it was in an old YMCA, and we had to lay out the mats before each class, and put them away afterwards. The mats didn’t fit the floor, and didn’t have that puzzle piece shape, so they would slide around a bit. And sometimes there would be a gap between the mats, so Sensei cautioned us to be aware, lest time wound all heels.
For Achilles, time wounds all heels.
