If you are 5'11'' (and over the age of 25)
let me just say this much:
you're too big for the playground's tunnel slide!
You might end up chasing your baby girl, thinking you can still maneuver down the slide the way you used to play "crack the egg" when you were little, follow her down the slide, and two hours later you will find the pain in your low back is still intensifying, you will have trouble walking up the stairs or bending down to pick up the toys, and you will moan like an old fart who threw out his back...
Thirty minutes later you will be calling your dad asking, "what the hell can I do to make it stop??" Then your mind will begin to race, (blurring out the doctor's voice), and instead of hearing "ice it and you'll be fine," you hear, "you will be in a wheelchair for the rest of your life"...suddenly you find yourself wondering how you will ever drive a car again, or run along side your daughter on her bicycle when the training wheels come off, or attend your son's high school football games when you can't even stand up!!---and ultimately you'll decide that your life is just about over.
My advice? leave the sliding to the kids and you'll be fine.
