let me explain this. If you travel to Japan or Korea..you will see some people covered their mouth with mask when they are ill right? It means they didnt want to spread their virus to other human. That person care about other person well being.
I think different cultures have a different concept when it comes to individual freedoms vs social responsibility. depending the types of mechanisms society uses to reinforce collective well being, it may seem odd, sometimes it can be off putting for those unfamiliar with the setting of the society, without the proper context it does sound weird or sexist for those unfamiliar.
