I have two series of pictures to compare, the first one taken in March 2005, when I was 39, and the second one taken last week, at 47 (going on to 48 in a couple of months). Changes are clear, but they are not all negative. Body weight is almost unchanged, maybe up a couple of kilos but hard to tell in the statistical noise. I expected worse, and there are compensations. See you in 2021.
