Living in the UK for 16 of the last 20 years, I am resigned to being interested in soccer, given that the only other alternatives are lawn bowling, curling, darts, badminton, European Tour "golf", Grab the Balls of your Team Mates and Opponents (rugby), and field hockey. In soccer/football I choose to support Cowdenbeath, figuring that their nickname, the "Blue Brazil" indicates that they are both Protestant and Catholic, even though this is probably not true, but I love the town anyway..... I also support another losing cause, Scotland, although as Patrick Kiser will know, we kicked some butt in France a week or two ago. Just so I can have some regular does of success I also support Man United, and revel when they (usually) put clubs like Arsenal, Liverpool and Chelsea in their rightful places, below the salt.
As for the US, I can't help continue to support the team of my youth, the Yankees, and most Octobers I thank the lord of the championship rings that my parents moved the family from Boston to the suburbs of NYC when I was age 3. I also check in every week to see how my alma mater, Stanford is doing. This weekend, when they were leading Oregon 31-24 at halftime and lost 31-55 was not atypical of most of the 40-45 years of my support.
Outside of sports I am an information and crossword puzzle junkie. I competed in the latter when my synapses were sharp and my small muscle control adequate (at the highest levels, how fast you can write is critical, as you and all your opponents can think at about the same speed). Nowadays I just do 2-3 a day to try to delay the onset of Alzheimer's. Similarly, where I was once a world-class wine drinker, I now focus on quality rather than quantity, in deference to my liver. I sing, too, chorally and as a solo, although the latter is only when I break the quality/quantity rule mentioned immediately above.
I'm sure there is more.....
