That "l'm going home" is inspirational!!! I have been lucky all my life in too many ways to mention without sending you into a coma, but my decline started around 2yrs ago when l was 67. The main thing was a f8cked up right hip that stopped me even walking more than 1/4ml without chronic pain even though l'd loaded up with pain killers beforehand.................(I had known of my disintegrating hip for a few years before, but just kept putting it off thinking "it will get better!"....Yeh!..Really! In the meantime l decided to climb a river pebbled steep incline with all my biking gear on to get a good shot of my bike down by the river, well, not my best idea because coming back down my leg shot away from me, then gripped into the hillside, & then go under & backwards at a rate of speed so unbelievably quick it ripped my quad muscle from my kneecap!!!.....Took off my long sleeves T shirt, wrapped it tightly around the already swollen leg, pulled back up my biking trousers & rode the 100mls home with a straight leg sticking out from my bike.....( my wonderful physician said it was a ham string injury, but that's another story for maybe another time) That diagnosis delayed what should have been immediate surgery to surgery where it was touch & go if it could be repaired, but l went & had the surgery, & all l can say is that after 6 months it still doesn't feel right, but l get around. Then after putting it off for too long l elected to have a new shiny metal right hip inserted (after they'd sawed off the old one of course!) That was 4 weeks ago, & this is where l get to compare myself to the "l'm going home" geezer! I got to pushing myself without using a physioterrorist, & progressed quicker than the Hip Replacement Guide Book suggested & got into the truck at 3 weeks, then the car a few days later, then at the 4 week mark l managed to get my right hip swung over the 'bike & go for a 100ml jaunt around the (thankfully) deserted countryside on a beautiful day.........................& that my friends was my "Yahoo!" moment.
