I did a couple of things for my 50th.
1) went clubbing with some old clubbing mates (two of us were 50 so we joined up) it was ace. Most of my clubbing these days is limited to random small invite only events and very low key – more chill out groove by a pool stuff) So this one was great, we went to Fabric en masses and annoyed all the hip and “too cool to move” trendies 👍😜 I even wore my Stetson I bought in Ibiza back in 98’ 🤠🤠
2) had planned a sailing trip around the eastern Italian/Croatian coastline, just us two a 50fter a bucket full of euros and a grin and not much else.
Have to say neither events were “planned” per se more just “yeah, sounds good”. I also had a little “what are you going to do for your 50th?” And each time answered “I’ll think of something”
Like 80% of stuff in your life, choose what you want to do and enjoy it. Guaranteed you’ll die one day and the odds are stacked against you as you creep closer to the inevitable.
