So quite a lot of my practical experience and exposure to wonderful people and places has been a function of the travels of the emergency medicine guy. Practical tips and advice for anyone – from navigating a busy European airport to getting around Africa. Speaking of which – I have been to just about every country in Africa, swum its rivers and oceans, climbed its highest mountain (Kilimanjaro in Tanzania), had coffee at its lowest point (in the Danakil depression in northern Ethiopia) and crossed its driest desert.
