10... 9... 8... 7... 6... That's about as far as you get, counting backwards, as you wait for surgery to begin - and that's all most people know about what I do. But what happens between you conking out and waking up? And what does the anaesthetist have to do with it all? Do they just sit around playing sudoku while the rest of the team do all the hard work? And why are they so obsessed with what time you ate dinner? Join Colin Black on his journey from accidental medical student to HSE and NHS trainee and, finally, Consultant Paediatric Anaesthetist at the largest children's hospital in Ireland, where any given day could end in laughter or tears - and that's just the staff. Razor-sharp and forthright, Gas Man is a disarming and frequently hilarious account of life in one of the most fascinating and thrilling professions at medicine's frontline, where every day is a heady cocktail of severe pressure, poignancy, and profound social awkwardness.

In addition three new chapters have been added to describe the new advances in the relationship between climate change adaptation, rural development and how trees and agroforestry will contribute to a likely reduction in vulnerability to climate change in developing countries
