The median is the middle number when the numbers are arranged least to greatest, which they already are.

Take numbers away two at a time, one from the front and one from the back.

1,2,3,3,3,8,8,11,15

2,3,3,3,8,8,11

3,3,3,8,8

3,3,8

This means that the median is $\boxed{3}$

Using proportions, it is found that the life span of the person would be 14 years, 212 days and 22 hours shorter.

---------------------------

2 packs a day for 35 years is 40 cigarettes a day for 12775 days, as $35 \times 365 = 12775$ .
Thus, a total of 511000 cigarettes, as $40 \times 12775 = 511000$ .
Assuming each cigarette costs 15 minutes of life, the person loses 7665000 minutes of life, as $15 \times 511000 = 7665000$

One year has 525600 minutes, thus the person loses 14 years of life, as $\frac{7665000}{525600} = 14.5833333$

Looking at the decimal part, the person loses 212 days of life, as $0.5833333 \times 365 = 212.916666655$
Again looking at the decimal part, 22 hours, as $0.916666655 \times 24 = 22$
