I think the bubble should say: there name, age, d.o.b, relationship status because then other people wanting to meet new people could read there bubble and know a few things about them already.
This would change our lives because we could meet heaps of new people and you could meet the people who they really want to meet.
Because then you could meet people that have common interests and know what people are actually like.
Yes because it will give you a better idea of who or what people are.
