As we age we do notice changes to our physical beings and our attitudes will inevitably change too, but not always as we expect. My body is older and I know it. My mind is sharper and I am kinder than I once was. Because I am aware of my mortality I am doing everything I want to while I can. It is freeing to be able to accept what I can't change and invigorating to do things I would never imagined even ten years ago.
I am pretty open about my frailties, but you don't have to be. You can share or you can be anyway you want. I was generally arms length when I was listing and selling in earnest but now I don't have to worry. There are always surprises. I choose to embrace them.
