Thanks, allrighty. I actually googled it to see if there was any interpretation of it- didn't see the 'all by myself' bit because I got sidetracked in a discussion on world poverty and waste collection - lol- some group project that my son has spent hours on at Uni.
All the Unis now seem to have a 1st year engineering unit focusing on some 3rd world country's problem and how to solve it. Usually some sort of waste management- one son designed a product made from recyclable material, my second son is now designing a waste dump for a place in Cameroon. Hours and hours and hours of work- I'm sure you know how fascinating group work is.
