Some of my favorite and earliest memories are those of being around greenhouses. I remember visiting my Granddad every weekend in London, England. He lived in an apartment in London and all the residents had their own little garden out the back. My granddad had built a fish pond and greenhouse in his little garden, both were well used. And the best thing about going to visit Granddad for Sunday dinners was that the first thing I got to do was run out to his little garden and feed the big goldfish in his pond.

Here’s a disgusting thought.

Did you know that up to 80 per cent of the dust in the air you’re breathing right now (assuming you are sitting inside) is made up of dead skin?

It’s true.

Human flesh is the most common form of dust in the air, and makes up the bulk of what’s known as “indoor air pollution”. So far, over 350 different types of indoor air pollution have been identified. Some common ones include pet dander, viruses, moulds, pollen, cleaning chemicals, and solvents from furniture, construction, and clothes.
