If religion/politics did not exist what would we talk about? Sports, science, poety, music, animals? What is YOUR favorite topic? Why?

Religion and politics does exist and it's still the most boring and vapid thing to discuss or obsess about.  In all reality the two most base and uninspired topics to discuss.

To answer your question?   Science, humour, lifestyles, music, general philosophy.

I can live without religion and politics. What I talk about depends on who I'm with. Sometimes you find a topic of mutual interest and the conversation just flows; at other times it's like pulling teeth.

Hmm, not too many talking about motorcycle flattrack racing here. I'll have to go with the common subjects.
