Seriously though? "Untimely demise?" I mean, she could have tripped stepping off the curb crossing the next street and suffered the same thing. Not to be morbid, but at 87, life is, well... fragile.
And fragile things take extra care and if that means staying off of busy sidewalks less one gets bumped and fall then one stays off busy sidewalks.
Sorry guys but the old lady was being negligent by placing herself in a situation on a busy sidewalk where she could be bumped and injured from a fall. Don't know if dying from complications from a broken hip is in the top 5 of old folk cause of death but I'd bet money it is in the top 10.
Oh - and GlocktoGo - to answer you comment about me being pretty close to training wheels on a walker I'll tell ya - when I'm in my 80's (good chance of making it that long - my ancestors typically lived into their mid to late 80's, 90's and one to 104) I won't be putting myself into situations where my age would put me in peril.
