Some examples:
A ring slides on but gets stuck trying to take it back off.
A kid puts his head through metal slats on a railing, but can’t pull it back through.
A girl gets her body in a clothes dryer, but can’t get back out.
If we can fit forward, shouldn’t we be able to fit backwards, too?

With fingers, your fingers aren’t exactly the same size all the time. If you are really warm, for instance, they might be ever so slightly more flush with blood.
The real problem, though is that arteries, which take blood away from your heart to your extremities like fingertips) are DEEPER inside your body than the veins, which take blood from your fingertips BACK to the heart. Also, arteries have more blood pressure than veins. Blood in arteries in being pumped, blood in veins is flowing gently back.
So, say a ring can go on, but is nice and snug. if it is a tiny bit too snug, the blood going INTO the finger is under pressure, and deeper where the ring is not compressing the vessel. However, the veins at the surface are NOT under pressure, and the walls of the vessels might be partly compressed. Blood is going into the finger faster than it is going out, so the finger out past the ring starts to swell up with the extra fluid. As the finger gets a little bigger, the problem gets a little worse, right? now the ring won’t fit over the knuckle.
In the hospital, we use a technique where you wrap a string tightly around the finger just ahead of the ring to force the swelling out, then as you unwrap the string the ring advances over the knuckle.
