One of them is physical ability.
At my age I have some aches and pains,
but I am still able to move about quite freely.
Case in point; I yet again re-arranged my sewing room.
Bear in mind that I arrange and re-arrange my home constantly. Its either a neurotic habit or I just simply enjoy the creativeness. (I choose creative ;)
Perhaps that is the exercise
that keeps me mobile? (heavy furniture)
One thing that is always important is
to have a good view from the window
for birdwatching.
And look who arrived as I was typing.
