Extra-cirricular

What if by the time my kids are 25 it is discovered that team sport is a horrible thing put kids through?

This is probably unlikely. However I am going through a process of trying to work out what extra stuff kids do? My kids do swimming lessons (although sometimes they are not too keen), play in a basketball team, and have done some soccer. What are the skills that are most important for them to develop? 

Here are a few categories:

Necessities

• Swimming basics so they can have fun in the water and not drown

Good for coordination

• Martial arts
• Dance
• Gymnastics
• Music lessons
• Team sports?

Good for creativity

• Dance
• Circus
• Music lessons
• Lego?

Good for socialisation / team work

• All of the above?

Not sure that helps me that much. I think my rule of thumb will be, if the kids are into it and it is not add stress and cost to my life I don't want, then they can participate. Otherwise it is a no go.
