I consider meditation anything that quiets my mind so I find some walks meditative, when I was younger, parts of my runs and lap swimming were meditative. Strangely, when it was hot in the house after my bath, rather than drying off, I chose to meditate naked. I focused my mind on the feeling of the drops of water evaporating off my skin just as I used to do after swimming in my youth then letting the sun dry me off on the pool deck.
