How often do you have ''deep conversations'' and do you think humans need to have such conversations once every while to survive?

Not that often anymore. Me and my former best friend used to have them all the time, sometimes a few of us would talk the whole night solving the worlds problems and having real deep conversations about stuff we wouldn't tell anyone....right now, the only reservation I have about not having deep conversations anymore is probably not being able to connect with someone in a more human and intuitive level stripped from materialistic and ego driven social situations
