We’ll be posting occasional interesting snippets from the world of healthcare designed to tickle your little grey cells (as Hercule Poirot, perhaps the greatest detective of all time, called them). They may be taken from novels, memoirs, blogs, podcasts, or the thousands of healthcare-focused websites strewn across the internet.
The first one is all about something many of us are suddenly much more expert on that perhaps we expected to be.
Did you know…
Viruses … are the most abundant life form on Earth – there are more viruses in the world than all other forms of life added together. (They) ‘have invaded every niche occupied by living things, including the most inhospitable places like hydrothermal vents, under the polar ice caps, and in salt marshes and acid lakes’, writes Dorothy Crawford, Professor of Microbiology at the University of Edinburgh.
We are taught to think of cells as small; the average human body, for example, is composed of 37 trillion of them. This helps put bacteria in perspective. Each bacterium is a single-celled organism. Ten thousand of them would comfortably fit on a grain of sand. But viruses make bacteria look like giants. The volume of a virus is around a million times smaller than that of a bacterium. So tiny are these most enigmatic of microbes that they remained invisible to the human eye until the invention of the electron microscope in the 1930s.
This extract comes from ‘Breathtaking’, the mighty impressive book written by Rachel Clarke about her experiences as a doctor in the UK’s National Health Service in the first months of the pandemic. Insightful, compassionate, angry, heartbreaking, and beautifully written, every bookshelf should have a copy.
