From a young age, Olivia experienced strong feelings and urges. She needed to kick the bin ten times. She would get into the car and tap the buckle with the seat belt ten times. She would lean forward in the front passenger car seat and gesture with her hands – opening and closing them ten times. She felt the need to do this before she could get on with her day. These urges were the consequences of genetic, biological and environmental factors. Patience and the maturing of chemicals in her brain saw her outgrow these impulses. Olivia is 11 now.
