Alicia you should take up cycling. Road biking. Not an impact sport like running, it's great for your body with relatively little wear and tear... you can feel like you're flying.... and any sport is likely to have a few SPs around (for the times you don't want to solo ride but instead socialize). I will help you pick a perfect bike as I'm pretty much a certified expert.
This is how you will find your SPs. Decided!
