After retiring in 2007, I have time for those things that waited and that list was long. The priorities switched around until I put amateur radio at the top and got my license in 2009.
I particularly like working digital modes and QRP. I spend a lot of my time building IQ SDR rigs and portable antennas as a practical solution to life in a community with deed restrictions. In fact, it may be the challenge that drives it all!
My other hobbies started with golf. I never golfed until I had been retired for two years. My neighbors got me to try golf and I discovered it is a social activity more than a sport. Now I am playing golf three times a week and bowling in a league, I am not good at any sport but it is fun.
