Welcome to 97-hour weeks. Welcome to life and death decisions. Welcome to a constant tsunami of bodily fluids. Welcome to earning less than the hospital parking meter. Wave goodbye to your friends and relationships. Welcome to the life of a first-year doctor. Scribbled in secret after endless days, sleepless nights and missed weekends, comedian and former medical resident Adam Kay's This Is Going to Hurt provides a no-holds-barred account of his time on the front lines of medicine. Hilarious, horrifying and heartbreaking by turns, this is everything you wanted to know -- and more than a few things you didn't -- about life on and off the hospital ward. And yes, it may leave a scar.
