What can I do on my 60th Birthday?

I was at a loss recently to know what to do for my 60th birthday. I had done LOTS around the date with various friends and family members including another visit to Abba Voyage, a weekend in the Forest of Dean, going out to see a UB40 tribute and a cinema visit to see The Sound of Music digitally remastered and whatever for its 60th anniversary (no I didn't notice the difference but it's still a damn good film so I would have gone anyway). All those things were amazing and I had an absolute whale - but on the actual day itself - when your birthday's on a Monday, what do you do? My kids have left home (sort of), my other half is not the type to want to go for a walk or do anything noteworthy or do a weekend away or anything I like. He suggested a trip to McDonalds.. A friend had offered to take me zip wiring - which I was up for but you have to book early and as I had only just had the news about my dad the time we were about to book, I wasn't sure where we would be with him so we couldn't book anything. I fancied a tour around the roof of the principality stadium in Cardiff and maybe an abseil from the roof or a zip-wire down, however they aren't doing these tours at the moment. I fancied taking me to see Abba Voyage again - but they're closed on a Monday and I went only a few weeks ago. I fancied seeing Phantom of the Opera in London but when I mentioned it another friend said they would like to come with me but were working on my birthday. I have never climbed Pen-y-fan mountain in Wales. My cousin, good sort that she is, offered to take me up there on the day, however I have a strong sense of self-preservation and so politely declined. So - I ended up using my free bus pass :( and going for a trip to Barry Island. The place made famous by Gavin and Stacey. I went there many times as a child and I like a good walk along the beach. I dipped my feet in the sea - time will tell if my survival instincts are working - the sea was brown with brown froth although the water wasn't too cold. The weather was lovely and while I was there I had a Happy Birthday call from both of my daughters which was lovely. I had chips for lunch with lots of salt and vinegar. I finished the day off with a visit to the Llandaff Cardiff Rock Choir and had a good singing sesh with my mates there. Nice and simple
