45 this year.
I’m grateful that my body is still working well. I don’t really have any aches and pains, apart from my right knee, which lets me know when I’m not getting enough exercise. So that’s quite handy really.
I’ve gained weight, I suspect due to medication, but I’m not horrendously fat, and DP certainly doesn’t mind.
Professionally, I’m so happy. I’m self-employed, doing a variety of things, all of which I love. Don’t earn much, but I have no mortgage so that’s ok.
I don’t look bad. The extra weight plumps most of my wrinkles out, and Botox deals with the rest 
Sex drive is fine, so far.
I’m making time to do things that make me happy. Read lots, have started drawing and painting and have discovered that I’m quite good at it. Yoga is one of my favourite things to do, and it helps keep me flexible and strong, as does my allotment. And I’ve surrounded myself with dogs, who, I’m finding, are so much nicer than most people.
My kids are adults now, and are a joy. No more foul teenage nonsense!
There are stresses - old parents to wrangle being the biggest. But after a horrible marriage which ate up my twenties and most of my thirties, I can hand on heart say that my forties are my happiest decade so far.
