Would you give your seat on a bus to a pregnant woman or an overweight woman?

I was inspired by a gaggers question earlier and wondered pregnant women for sure are given a seat but what if there was a heavy set woman that had trouble breathing and standing up... an interesting moral question...

To be clear it's a choice, you can't give the seat to both. Only one

I did put this as an update already and some got the spirit of the question. You are on the bus and you only have one seat, you have an overweight lady breathing heavy and struggling to stand on the left or a pregnant lady standing on the right, it's both ladies which takes out choice of gender, you choose who gets the seat, it can't be both. It's a moral delima
