Men- Do you wear T-shirts at home?  

Well, in my country, its very warm and its getting hot due to global warming, so every time i go to someone's place i see men without their shirts on(not women of course), It has become a very usual practice that they don't feel ashamed of exposing their body even if it it fat and ugly

Ah ok! Same here in our country and men not in their shirts became a normal scene especially during hot season or summer. But there is an area here in our country that discourages men not to wear shirts. Their attention will be called by the local officials for them to wear shirts--- to be decent even at home or while along the street.
