A refresher course in electronics for me would entail a complete repaving of my long gone brain !

It's all still there! Refreshing is like repaving.

The old road is like the foundation for a paving project. A fresh surface coat gives the foundation a new shine! It's a good metaphor. Refreshing our brain cells is good exercise! Any thoughts or questions are welcome!
