The hot shower featured prominently in Nomad's writings about sustainability and civilisation:

It's remarkable how little one really needs for hiking in the bush. Good shoes and a proper backpack are half the enjoyment. A good bed-bunk and a hot meal at the end of the day: also important. Practical tools: a hat, a pocketknife, a compass. But the one thing everyone, bar none, craves for after 2 days of hiking: a hot shower. I can only conclude that showering (or bathing) has become part of who we are. We can no longer go without.

After diverse other accidents, he was sitting freezing in a bus stop in a town a day's ride from Paris, when a hippie came by, and told him: "Why don't you come with me & stay at the farm of my uncle for the night? There is hot shower!" (My friend: "In those days, I didn't dream of girls or something, I dreamt of a hot shower!" -- Nomad's rule of Civilised Luxury No. 1 seems to hold.)

what are the bare bones in today's society? So I drew up a shopping list. It is not that different than DeAnander's list, and I used my South African experience to re-evaluate and Africanise my nomadic wish-list from Sweden.

Hot water - for my shower and my shave

I favour the approach of smart and sexy solutions with the corporation of certain western commodities and privileges. Clean water, a warm house, a hot shower with the push of a button - why should we not be trying to preserve those at first? Once we fail to do that, perhaps DeAnander's return-to-innocence scenario might play out. But I'm unwilling to move straigh there as long as there is the chance to opt for the first scenario.
