Examples

# Example 1: High Risk
# 60yo Male (+11+1), BMI 31 (+15), FamHx (+5), Ex-Smoker (+2), No Rx
# Score = 12 + 15 + 5 + 2 = 34
cambridge_diabetes_risk(60, "male", 31, 1, "past", 0)

# Example 2: Low Risk
# 40yo Female (0+0), BMI 24 (0), No FamHx, Non-Smoker, No Rx
# Score = 0
cambridge_diabetes_risk(40, "female", 24, 0, "non", 0)
