Brick is not good....This may sound stupid, but, you may want to pad those area with cow mats. I have a cow mat outside of my patio door. If I do go down, at least I hit a rubber surface.

My daughter suggested I tile my kitchen floor (oh so trendy).....I gave her that look....I think 'Cork' is more up my alley.

Given you broke some ribs once....maybe you should consider having some xrays??? You know how bad it is to hit the ER on a weekend.
