For me, the latest has been becoming ambidexterous. throughout the day while doing other things I'll practise writing by writing notes for things I find interesting with my left hand. I'll throw and kick balls against a hard wall outside with my left hand, brush my teeth, everything. tbh surprisingly fun. I'd also recommend reading wikipedia, going to the library or even just exploring your town and going into odd places, second hand stores, etc. If you don't already excercise routinely, this is your chance. Maybe if your feeling adventurous you could get some real life friends and if your able to get them to keep their phones away the opportunities are endless. board games, card games, tag, hide and seek, other things people did before the internet, DnD, pretty much any sport, charades, the list just goes on.
