A study published Thursday in The American Journal Of Medicine determined that it is highly detrimental to the physical and mental health of human beings for them to spend any more than five consecutive hours in each others company. Our research shows that humans are not evolutionarily equipped to handle being together for extended periods of time, under any circumstances, said the studys lead author, Mark Hughson, adding that the findings applied equally to both casual acquaintances and immediate family members, including mothers and their newborn children. We found that, optimally, people should limit themselves to between two and 20 minutes in another persons company, with five hours representing the absolute maximum amount of time that anyone should allow themselves to be in the presence of others. In addition, they should permit at least three days to elapse in between human interactions, preferably a week. We simply werent constructed to put up with more than that. Hughson went on to say that while humans had the capacity to withstand each others company in five-hour increments, it was ideal for them to isolate themselves permanently as early in life as possible.
