I have posted about this before, but thought I would mention it again in a related context. One of the 'no-mind' [*] activities that I engage in quite often is ironing my clothes. It's usually a mechanical activity, and I don't give much thought to it, but looking back over the years, and paying more attention recently, I realise that in addition to getting to wear neater clothes, I have benefited in other ways as well: for someone like me who spends most of his time in left brain activities, the fifteen or so minutes I spend ironing a shirt provides my mind the rare opportunity to wander unfettered. Mind you, this is different from meditation, where the objective is to quieten one's mind. The benefits also seem to differ from the rest obtained by the mind from a good night's sleep.
[*] I am using the term 'no-mind' in the inaccurate, but nonetheless common, sense. It has a wholly different meaning in Buddhist philosophy.
Related thought experiment: how would it be like to go through a whole day without any kind of verbalisation: no talking, reading, programming, not even 'thinking in words' (i.e. practising the real 'no-mind')?
