How strong is the nose 8 weeks post Rhinoplasty?

I had osteotomies, cartilage in tip and some sort of grafting...not sure I understand what the grafting was that happened. It's a revision. I am reading that contact sports are okay after 6 weeks. I don't play sports but I live in a city with crowded subways and am just so afraid of being hit or putting too much pressure on nose through kissing or something and trying to remind myself it's strong at 8 weeks. But is this really true? Worried the cartilage will get displaced also
