· I've had a good life: worked hard at what I can do well and was useful (teaching physics), travelled widely (including taking my family to live in India 1988).
· For nearly two decades I've lived on very little: NZ$1,850 or US $1,350 in 2004-dollars (or: sharing household expenses with my wife: NZ$7,490 or US$5,208 per person per year in 2007 after getting universal pension).
· My life focus is on minimising my ecological footprint, putting greater effort into this while the world's total ecological footprint exceeds the biologically-productive land and sea by an increasing amount.
