Probably not a good idea, so I won't recommend you to try. IF it does choke you, which prob wont then you are fine. But that would mean it would have to be really strong. The rope would suddenly work like a line. The line would ultimately slit your throat. Normally that would be quick, but that is because someone is pulling the line towards them. This on the other, is gravity trying to pull you down. There is a high chance that the line would cut a little bit into your throat and just stop. Blood will splutter everywhere and you would die in roughly 10 minutes. Depending on how deep the cut is. If the cut is small, you could still save your heart from pumping excess blood by putting a cloth on the bleeding neck. If it is too deep, then its going to be painful. Very.
