I was passing by and i was asking myself which sport you like the most.
Personnally, after a few emotional research, i decided to chose running. Because you can run alone.
Tennis would be a lonely sport, but there is some case in which you lose... And this can be the source of hazardous emotional stress. So you can play tennis if you do not understand the interactions very well. Personnally i would not consider playing tennis because my lawyer disadvises this.
Collective Sports would include some sense of groupwork, and the presence of some leader and of political interactions. Obeying only to my most gracious self, collective sports are excluded.
To avoid any feeling of defeat, hierarchyzation, compassionization, the number One rule is self protection.
I therefore advised myself to chose running. For a more peaceful sport practice.
Nevertheless i would accept to play tennis, or collective sports if the players and other teams submit to peace.
