Tough decision?

A deadly virus outbreak has suddenly contaminated the earth and some survivors were fortunate enough to avoid the fatal contamination by holing up in securely-sealed habitable underground chambers. In one such chamber, there are 10 people holed up waiting for the virus outbreak to end. These people are composed of the following: 1) a scientist, 2) an eminent educator, 3) a priest, 4) a young bright boy, 5) a physician, 6) a young pretty girl, 7) an old woman, 8) a pregnant mother, 9) her husband, and 10) you. The virus outbreak is estimated to clear up in 100 days, after which the survivors in underground chambers can safely move out.

Unfortunately, the food stocked in this particular chamber where you among these 10 people are holed up can only accommodate to feed 5 people in 100 days. You have been recognized as the natural leader of the group, and as one of the 10, has been unanimously elected to decide your group's fate. You are obviously faced with the hard decision of choosing who among you should stay in the chamber and survive by partaking of the food sufficient enough to feed only 5 people comfortably for 100 days. The rest might be immediately let out of the chamber to fatally face the virus outbreak and die immediately.

What would you do? If you had to choose, whom would you choose and why?
