I have been thru a horrific labor job, a chef, bs landscaping work by myself, retail (twice) and now mind enhancing (or dehancing?) work that is the postal service. I would say I prefer being mentally tortured than physically (even tho I am slender and in shape). At times I do feel physically exhausted from all the driving and extreme details the mail gives. It does help that my pay deposits are quite good, makes the mail a tad more tolerable...
