One of the reasons we all need to sh!tcan the OE rubber stems is because too many of us would just jam the air chuck on the rubber one handed, bending it around, leading to cracks at the wheel in aging stems (and long miles at speed with heat).
The only safe way to air up OE stems is with both hands, one holding the stem straight up against the chuck in the other hand. And that requires you to get all the way down on the ground.
Like you said earlier, us old guys can get down just fine (those with original knees anyway), it's the getting back up that sucks.
