I haven't played in 12 years, and since then I've had some pretty bad injuries. Destroyed my left ACL and haven't gotten it repaired. I've also had some severe lower back problems (herniated discs) that required cortisone and rehab. But at this point, at age 35, I'm pretty much cautiously functional.
Recently, though, I went to a party where someone had a basket and a couple discs in the backyard, and I just tossed a few, and my heart leapt! I forgot how much I love the game! So I'm looking to come back to it, but I want to do it safely. Any advice on how I should modify/play the game given my medical history? I used to be all about backhand power with the viper as my go-to driver. From what I understand, the game has changed, at least driver-wise, it seems.
I'd like to have fun, be competitive and be safe.
