newLife() -> spawn(newYear,happiness,[]).
happiness() ->
    WorkPid = spawn(newYear,work,[]),
    HealthPid = spawn(newYear,health,[WorkPid]),
    HealthPid ! go.
health(WorkPid) ->

            health(WorkPid);
        ill ->
            io:format("I'm ill..."),
            WorkPid ! {self(),stop}
    end.
work() ->
