  1. Note: Assuming half-lives of 5.32 years for MI, 4.78 years for stroke and 13.32 years for COPD [15]. Half-lives for stroke and COPD are age-independent, but for MI are not, the value selected for MI being for age 50–59. Expected ER ratios are 0.629 (quit 5 years) and 0.396 (quit 10 years) using the half-life of 7.48 for age 60–69
