+1 on health. I'm way older than both of you. Clean living and regular, vigorous, exercise has been the #1 key to loving yourself, confidence and mental health. Pays huge dividends later in life. As for relationships. As the old saying goes "If you are looking for a trout, don't fish in a herring barrel". Do what you want to do, travel where you want to go, join and participate in hobbies that you like. Group activities will be best (hiking, exercise, walking, tours, photography), You will meet your peers. good luck
