I would like to do a simple "wisdom of the crowd" experiment.
Can you please estimate: How old is the longest continuously operating commercial business in the world?
You do not need to do any research on this. Just give your best estimate.
Enter the number of years here. http://jpm.li/249
I will post the results of this little experiment here on the community.
Many thanks in advance for your participation.
