I've been spending a lot of time on learning martial arts, which was a thing I studied before becoming a JW in 1984 and only recently picked up again a little over a year ago.
Although my dojo is closed during the lockdown, I have plenty of time to practice in my local park. I'm limited practicing alone, but there are many forms and kata that can be done solo.
I practice bujinkan budo taijutsu and also Okinawan bojutsu. When I first started, I was somewhat self-conscious, but after going to the same spot three times a week for four months I've gotten over that. The regulars—including the local police—always wave.
A few curious people have stopped by and asked me about it, but most people tend to stay away when your waving a 3 foot (1m) sword or a 6 foot (2m) staff.
It keeps me in shape and develops good discipline.
