On retiring I realised I can satisfy my Insatiable Curiosity in all those areas where it had been constrained by the need to get the job done. Mechanics, Physics and Art could be added to my video electronics and product design skills.

I am happy that dancing is again cool - it was always fashionable - and also that I am no longer alone in thinking the bicycle is one of the greatest transport innovations. The e-bike comes a close second, even if considered only for those with knee injuries.

Don't get me started on preventative epidemiology, social manipulation, Brexit, or pangolins!
