If you have the balls to HODL over cycles and are still here now, you have the balls to do anything, my friend! I am also entering that age, last year I "missed" two trips that I had planned, just because on the day I thought "I just rather stay at home", but that was not fear or anything, it was change of preferences and my own "right to choose" of what would make me happier. Come to Spain, eat and drink like the locals and go back home to your family with a smile in the face!
