I occasionally lift 40-50 lbs (bird feed bulk bag), but more often I have someone help me or work out some way to move it without lifting.
A stent creeps you out? Would you rather do it the old way? Strip a blood vessel out of your leg, open your chest, spread the ribs, stop the heart, put you on a heart/lung type machine, sew the leg vessel in place to bypass the clogged artery. Hope you can start the heart again--When, there it goes. Then recooperate for a year with some possible brain damage. Which is better, a stent or bypass?
...and then, learn to breath again after they collapse your lungs....
