Mine is spas or spa days. I used to love them. Went to one recently and was so bored.
Dh and I camped (tent) recently and the place was so peaceful and beautiful I realised I enjoyed this much more than spa days or stays. The weather was good admittedly. But even so walking in the beautiful dales was so therapeutic. Also the wild swimming under waterfalls was blissful. Dh and I often camp but have found the best site. Cost less than £60 Inc electric hook up. First time we've used electric.
Dh and I walk lots. Loads of long distance walking. I also walk with friends. So it isn't a new realisation that I love the outdoors. Just a sudden realisation that spa days bore me now.
Have you outgrown anything? Or found a new love of something?
