I’m heading towards my mid thirties. Yeah, not so old just yet, but things are definitely not working like they used to all of a sudden!
I am suddenly aware that there’s a good reason you don’t see someone over a certain age sitting with their legs curled under them in their armchair, my previous favourite way to sit. If I do that for more than ten minutes these days, it takes me about half an hour to get up and another ten minutes to hobble to the bathroom while my legs try and get back in action.
Also, my hands!!! Where did all those veins come from?? Are those little freckles REALLY the beginnings of liver spots? How did this happen?
When I look in the mirror, I still see (blindly and foolishly) a girl of, oh, maybe 23 or so, who still weighs less than the average school bus and who doesn’t have crow’s feet the size of Europe.
I wonder what I’ll see ten years from now? Maybe I will post then, yearning for the day when I was 32. Actually, I’m sure of it!
I’m not sad- goodness knows I did ALL the living I could have done in my youth, and I don’t regret a thing- just incredulous!
