How many men live inside one man?

I always believe that there are more than one man inside one man, just like tree spread its branches.
Sometimes we laugh, sometimes we cry, sometimes we play, sometimes we share our intimate feelings, sometimes we ignore, sometimes we are jealous, sometimes we are helpful, sometimes we are greedy.........Hasir niche kanna emni orei din jadi jai jaak naa...(bengali)
Are these different emotions of different moments or different man in different time lives among us .
I do not know the answer but I guess thats why life is beautiful.
