I believe the second smarted aminals are dolphins, and they DO eat meat.

In regards to the actuall topic at hand, my friend smokes a few times a week, but he runs 2 times a week and does free-weights 2 times a week (i.e. monday: run, tuesday: free-weight, wednesday:rest, thursday:run, friday:free-weight, sat/sun: rest). He seems to be in pretty good shape.

On the other hand, I know someone who smokes every other day, does nothing but read, and is the tonest person I've seen in town.

So maybe you should... read?
