Math on suicidal willingness

Well, this implies that everyone has some sort of suicidal willingness, otherwise A=0 so you weren’t born yet or H=0, which basically means that your dead. It also implies that two people with the same age, physical health and breath hold capacity always have the same willingness to suicide.
You could probably imagine it to be something like:
t / B = k * H / A + j * SW
So B would be the maximum time you can hold your breath in a non-suicidal condition and thus if t / B >= 1 you are strong enough to suicide by holding your breath. With SW=0 you are in some sort of “natural condition” and t should be way smaller than B. You could for example take your body mass index BMI as H (this is obviously not sufficient, but for the purpose of simplicity…) which should be on average something around 20 and your age in years for A (this also is not sufficient since you can’t hold the most breath when you were just born and the least when your about to die, and in between it is not linear).
Lets say you are 20 years old, your maximum breath hold time before you die of a lack of oxygen is 15 minutes and you are absolutely sure you will commit suicide (SW=1, just hypothetically). This gives us:
15 / 15 = k * 20 / 20 + j * 1
Lets say A=20, H=20 again, but you are not willing to suicide at all (SW=0). Then you said you are able to hold your breath for t=1/2 minutes. This gives us:
0.5 / 15 = k * 20 / 20 + j * 0
Solving both equations for k and j results in:
k = 0.033 j = 0.966
So if you try to hold your breath for as long as it is possible and measure the time, with this equation you can calculate your suicidal willingness:
t / B = 0.033 * H / A + 0.966 * SW
where both constants just apply to your body and age.

Now, don’t take this seriously, I don’t even know if you care much about stuff like that. But: You should not actually try to calculate anything about suicide with such a simple formula since the human mind is way to complex to be described by mere numbers. In fact, it is impossible to die of suffocation by holding your breath since you will black out before you die and reflexes will make you breath again. If you really want to improve your situation you should talk to people about it, that is the best thing to help you.
