Re: "One form of exercise a day"
Good thing you never use any bridges, or in fact anything that was engineered in the last 50 years - all of which have used modelling to determine how to build them.
supermarkets model demand for perishable items, and do a pretty good job most of the time - because on average we are reasonably consistent in our behaviour.
The model fell apart when everyone decided to buy groceries for three weeks at a time... but that'd not unexpected (well, the panic buying was, the model failing on that event wasn't).
