This book I'm reading about Yoga is really interesting .  I didn't know you did Yoga .  I don't really practice it regularly yet , I'm just learning about it .  What have you learned ?  Right now I'm learning about the importance of breathing slow , deep and regularly .  As opposed to short and shallow ?  Yes . It says here , ' He who only half breathes , half lives . '  I read something like that once . I think it was , ' Life is in the breath . '
