The Rosie Project by Graeme Simsion
Don Tillman, a genetics professor, leads an efficient, organized, structured existence. He has a standardized meal plan that alternates 7 menus – one for each day of the week. The benefits are that his shopping list is always the same, there is no unnecessary food in the house – only ingredients for the meal plan – thus no waste, and he can cook without thinking - leaving his frontal cortex free to work on something more important, like a science problem. He organizes his day down to the minute: 2 minutes for shower, unless he washes his hair (which adds an additional 87 seconds due to having to leave the conditioner in for 60 seconds), his martial arts training, his bicycle commute, and his lectures. An unexpected interruption could disrupt his whole day. Don has Asperger’s syndrome, which the reader comes to realize, but Don does not. He even gives a presentation on Asperger’s syndrome, but doesn’t see the similarities between the symptoms and himself.
