Looking at a previous post of mine (see here, "cereal"), I remember I wasn't able to even prepare a bowl of cereal on crutches. That part hasn't really changed ... you would only know if you've been on crutches. BOTH of your hands are full, all the time, so you can't do anything ... can't carry a cup of coffee, glass of water, book, etc.
But this time around I feel like a pro. In the morning I get up, put my knee on my wheeled office chair, and scoot to the bathroom to get ready. I even figured out how to get in and out of the shower on my knees, on my hands, on my butt, from the chair, from the floor, whatever. I slide up and down the stairs like I was on a playground ... AND ... the big new development this time around is this --- a knee scooter!
I WILL be participating in the NYC 13.1 Half Marathon in March. Now, I did not yet say I was "running" it. And no, I won't be "crutching" it like others out to prove something ...
