I'm sure you could get a squad of 10 of mixed ages and abilities to play amongst themselves on a regular basis. I have just jacked in 5 a side much to my dismay but our squads aree a right mix and from it, over the years, I have made some gret friendships and done some pretty madcap things on weekends away, as we take our footie skills on tour. Great stuff, wonderful for mind and body.
I love playing but with working offshore I can only play once a month which isn't enough for me. Sure we can get a mixed age team, I'm 34 and no spring chicken anymore.
