I'm sorry about your father and of course it makes one think about loss and mortality in general but it sounds as if you have childen who love you and that can be a great comfort. It would be surprising if you weren't emotional at such a time.
My husband was 70 this year and he felt like you while I, at a mere 69, am not bothered now. Even with the joint pains etc. and preferring my home to going out I somehow kid myself I'm young at heart. I felt my worst when I became 50 as that seemed a really big turning point and I was older than my father had been before he died.
I do hope you will soon feel better.
Well I am 61 and loving it, just started to lose a bit of weight and feeling much better for it, we have just re homed a flat coated retriever the walking helping towards the weight loss.
Two grandchildren to look after full time so can pretend I'm young again, swings,slides, sandcastles.
Just enjoying it.
I also am sorry to read about your loss. Guess these happenings are inevitable but they still hurt.
Must say I had to laugh when I read all the posts here. Old at 60? Come on! I am now 83 and still have my own teeth and original-coloured hair (mouse). I have outlived my parents and sister and still miss them. In my mind they still live and I'm grateful for all the happy and loving times we shared together.
Age is a state of mind, mind over matter. I don't mind, so it doesn't matter. I do believe in positive thinking and in visualisation so, I tell my mirror image I am pushing 70. Sometimes it works although my husband's new camera at times takes convincing. If the image is a good one I tell him it's because my heart is pure. LOL.
I believe I have said this before but I make a point of mixing with people who should have gone to Specsavers!!
