My family Doctor uses those old fashioned sliding bar weight scales. I doubt they ever get calibrated. When I've been to Urgent Care or Orthopedist my weight is just a few lbs off my weight at home.
About 1 or 2 which is probably accountable by clothes, shoes, wallet, keys, phone that I wouldn't have on me at home.
I'm always naked when I weigh myself at home. Usually rest my cock on the sink to knock off a stone or two...
Dayum. Got there before me. I love a good pebble beach themed arrangement in the bathroom Normally I treat it with more care than him though, apart from when i'm using the pebbles as anal beads
