Brought up in a family with a long heritage of striving for greater wellbeing he is passionate about simple living and slow food, made fast. Growing organic vegetables, rearing chickens both for meat and eggs and keeping bees are all part of that fervent and oft frenzied lifestyle; he is often known as attention-deficit Bernie. He can be a little on the manic side.

As a physics-graduate he has built his own solar farm and although still connected he and his wife Helen are in effect off the grid; harvesting rainwater is part of both his commitment to the planet and his family's innovation.

He and his wife call it building a Cyan Zone at their home; caring for themselves and the planet.

Post-chlorination of water is a subject that worries him not a little. The literature has much to say on the subject. Are we really sure that from the utility is only toxic for bugs and not us too? Whilst living in Chicago they found that from Lake Michigan was undrinkable.

They call it their green journey.

Backyard permaculture is his other life-long passion; working with nature, rather than against it to preserve both the planet and ourselves.

As a lover of good bread, conscious of all the literature about the virtues of whole grains and the downside of refined flour, he bakes a sourdough loaf daily using 100% wholemeal that he grinds himself.

Though in the middle of his eighth decade neither he or the good wife take any medication whatsoever. They attribute their wellness to the mountain of organic nosh from their garden, the fermented foods they enjoy and the whole grains they consume.

The whole subject of wellness has taken on a new meaning since retirement. Generally busy in their garden, they are physically very active.

The author Bernard Preston is still writing, though Priests Denied has stalled for the moment. Much time is spent writing for the local newspaper, a column entitled Our Green Home; and on this website.

He is active in his church where he is a layminister.

Dr Bernard Preston still sees a few patients every day; he loves his work. Helen, for her part, gives extra mathematics lessons to the matric level.



Perfect sleep is characterized by 7-8 hours of rest per night, getting up early and not going to bed late.

Insomnia, sleep apnea and excessive daytime drowsiness come into the equation too.
