weights
i've been going to the gym fairly regularly recently. it's the same gym i've been going to off and on for 20 years. but just the other day i noticed that the 5 pound weights have a 5 on the side that when looked at sideways kinda looks like a 10. i wonder how many times during that 20 years i thought i was adding 10 pounds when i was really adding 5 pounds. and i wonder why i never noticed before. could my eyesight really be getting that old? nah.
