Yes they absolutely are. I will provide an anecdote to this claim. Anywho, around mid july 2010, in deerwood minnesota, a bee landed on my boat in the middle of bay lake. Apparently, the lazy minnesota bee did not have enough energy to make it all the way across the lake without stopping. Most likely because it did not spend enough time flying and was out of shape. I felt intruded by the bee so I smashed the life out of the poor idiot with a towel. It is no longer lazy, now it is dead. Ultimately, the bee's laziness was the cause of its demise. In my main residence of orange county, CA, bees are hard working, disciplined, and honey-driven. Based on scientific evidence and personal experience, I deduce that any California bee could have easily made it accross without any need for rest.
