Dear Otto and colleagues,
If some of us TC6 members have a burning interest and energy to spare, why not? Otherwise, my feeling is that there are many areas, much more closely related to the core of TC6 activities where we could well use more energy --- but we don't seem to have this energy.
Nothing against sports: my own aim is actively participate in various sports activities six times a week. (I have to try to keep up with our daughters!)
Best regards and a good weekend all around, Harry
