Hi all I have been retired for ten years worked at the local Veterinary office for 21 years. We did large and small animals, did everything from clean floors, mow,answer phone,make appointments to giving shots preping for surgery to helping with surgery when needed. Loved every minute of it. Even cleaning cages.Before that I worked at a local building supply and could figure board feet in my head. I sometimes have to use a paper and pencil to figure yardage now and then still mess up.
