I am a very old man and take that into account. I used to play active games when young and middle-aged, but chronological enhancement has left me in a somewhat limited position in my old age. The following apply – or could apply – depending on how I feel at any one point in time. Nothing really helps much when enthusiasm and motivation are crueled by depression which, for me these days, is often the case. So:

• Jumping up and down on the spot to keep warm.
• Counting the steps I take on my iPhone 6S.
• Walking for the time it takes to boil the jug from turn on to turn off trime.
• Walking up and down the driveway of our house for a minute or two or whatevcer – as the case goes.
• Mopping the floor, vacuuming, cleaning, doing dishes, cleaning out shelves, wiping mould and dust off external walls, cleaning and wiping the stairs sets to our house – which is elevated.
• Singing songs to exercise my throat.
• Thinking through scenarios, writing poetry, doing blog and LinkedIn entries, and corresponding with newspapers both by letter and online comments to keep engaged.
