Hello, science people.
I have a difficult problem to solve and I know nothing about that kind of science so...
I have a heart "disease" ( https://en.wikipedia.org/wiki/Brugada_syndrome ) which means it is excpected to stop earlier than most people. BUT. I am actually absolutely impatient for that thing to happen for numerous reasons.
Problem, it is unacceptable for my death to be considered suicide.
What medecines or drugs should I acquire and take to just make it so that people think " Ok, so he had a Sudden unexpected death syndrome, his heart just stopped."
Please, help me.
I couldn't thank you enough. But I would try.

/Sci I don't understand
Tarzan and jane, whose total mass is 130 kg, start their swing on a 5.0m long vine when the vine is at an angle of 30 with the horizontal. At the bottom of the arc,Jane, whose mass is 50 kg, releases the vine. What is the maximum height at which Tarzan can land on a branch after his swing continues? ( Hint: Treat Tarzan and jane's energey as seperate quantities.)
P.E. = m1gh + m2gh
= 50x 9.81x2.5 + 80x 9.81 x 2.5
= 3188.25 N-m
K.E. = 3188.25 = 0.5 x 130 x v^2
v^2 = 49.05
v = 7.003 m/s Tarzan's Velocity alone
K.E. = 0.5 x 80 x 49.05 = 1962 N-m
(You could also do K.E. divided by The gravitational force [ joules divided by Newtons to get distance] but that is the same as this next step)
P.E. = 1962 = 80 x 9.81 x h
h = 2.5 m ans
But apparently you can just do MTgh+MJgh=MTgh
Solve for h and you get
h = 2.5*130 / 80 = 4.06
How are they different? I doesn't everything have the same free fall acceleration regardless of mass (I mean I guess tarzan did lose some inertia dropping Jane though idk)? It should be the same like in the first example but why is it different with the P.E. only answer? Isn't Mechanical energy conserved without friction?
Posted before but all answers where literally Idk why you got different answers with P.E. only vs P.E. + K.E.
Can anyone here help pleas, I really don't understand.
