Do you use maths in your everyday life?

In case you missed or, more likely, deleted the email this week, we are looking for volunteers for a series of short films about using maths (yours and maths generally) in everyday life, wittingly or unwittingly, or not at all.

So far we have had a LOT of cooking including bread and marmalade, but also pondering on how the plane you are sitting in is staying up there, and doing household chores in the most optimal way.

Email Dyrol (mathematically).
