This is heartbreakingly reasonable advice. (I play centre D so almost all the gameplay changes you suggest are my bread and butter. Probably time to learn a new position if I want to stay intact.)
Great advice on the workouts, probably safer to only play if I've been working out that week AND it's great motivation to actually go to the gym.
This was really well put, thanks! I'd actually been worried about the older age groups for much the opposite reason, the couple I've seen have been hard competitive with a lot of Europeans who used to play at higher levels. And I'm a 5 - 15 years older than most of my team mates so I'd have to join pretty much solo. But I imagine there are a bunch of different leagues of all abilities/aggression/competitiveness.
