That's my boat on the left, as the presenter walks into the workshop at the beginning. Rob Higgs is a genius, very inventive, and he's a thoroughly nice bloke.
He's totally right: to be a design-engineer these days involves sitting at a computer most of the time, whereas he's able to connect to all parts of his creativity.
Seems to be the case with most "brain" jobs as opposed to "hand" jobs (errm, maybe I should rephrase that ). I'm a software engineer so it could never be any other way, but my brother's a geologist and he also spends the vast majority of his time in front of a computer, usually also writing software code. The only time he goes out and hits rocks with hammers is when he's teaching the basics to undergraduates.
