That is what ramps and trailers are for.
Reminds me of my Grandfather. World War 2 Decorated Soldier. Lived through "more shit than you could imagine".
Stubborn old fuck confined himself to a wheelchair after his triple bypass at 88 yrs old. Worked himself into a crotchety old bastard, as was his right.
Idiot got his wheelchair stuck in the front doorway at the age of 93 and forced himself through same doorway and fell, hitting his head on the front steps. Languished in a coma, came out of it with total sensory loss, only to die a few weeks later.
War hero. Taken out by stupidity.
Don't do stupid shit.
