Well can I say my own logic puzzle?

There are two doors, each with a guard in front of the door. One door leads to freedom while the other leads to death. Also, one guard always tell the truth while the other always lies. You don't know which guard says what. You must ask 1 guard 1 question to learn which door to take. What do you ask?

Why not push the guard through the door and check if its life or death?
What if the guard is yo mama and the other yo girlfriend? What then?

Ask them what the other person would say is door to freedom. Take the opposite door

They would both tell you the other would say their door is.
The guard that lies would say the other guard would say door d (death) and the truthful one would tell you the other one would say the death door d

Here let me explain:
If you are asking the truthful one, he will tell you what the liar will say, which is the wrong door. If its the liar then he will lie and tell the opposite of what the truthful would say is the right door, which is the wrong door. Either way, choose the other door.
The truther will say that the liar will say his door (death). The liar will say that the truther will say that he will say the truth door.

Also we don't know which guard is which.

One of my engineering professors gave me this problem in one of my classes. It took me an hour to solve it. Now I want to share it with y'all
You have 5 jars of pills. 4 jars contain pill A and one jar contains pill B. Pill A weighs 1 gram while pill B weighs .9 grams. How can you find out which jar contains pill B with only one measurement?

Place four on a balance, two on each side. The result will tell you where Pill B is.

Or, place all five in water and measure specific gravity by seeing which one floats differently.
