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 . '
