It's easy for me to empathize with others because I used to be "one of them".

I certainly have NO problem with stairs or any other mobility challenge but I wasn't always this way. I was born crippled. Yes, crippled. Not "challenged" or "differently abled". My legs were born looking like pretzels (bilateral club feet).

I have NEVER forgotten what my early years in casts, crutches, braces and wheechairs were like or the post-surgery difficulties I had.
