Dr. Peter Rigney:

That requires a specific intervention. There are many things in third level education that one brings one's life experience to. Mathematics is not one of them. It is probably more difficult to learn mathematics at my age, in my 60s, than it was when I was 16. These things have to be worked at. If one is doing inspection and construction, there are certain things one needs to know about the laws of physics, for example, and how things fall.
