Lived in Lagos as a kid for 4 years and your report brings back fond memories! I'm a physician (non-practicing) myself and love to travel. Would love to get in touch with you and learn more about how you combine travel with medicine/scientific pursuit. Do PM me.
Btw, I've not heard of a "Mekki" market in Lagos; are you sure you didn't mean Lekki market? The one close to Lekki Beach?
