What hight I should jump from?

[spectraltease]

Like how high has a building or a bridge to be to overkill? I got a bridge near me, its 200m high but thats too high for me but we will see. In the night, I wouldnt even see the ground.
I search other bridges, but what is a good hight? 30m?

I don't think 30 meters is high enough (though there are people who do die from lower heights, just not reliably). If I remember correctly, 150 feet (45 meters) when the ground is solid and dense, and 250 feet (76 meters) when the ground is a body of water (lake, river, pond, etc.). Other factors include how you land (head or feet), your body's condition prior to the jump, how quickly you are found (whether you die of shock and blood loss or the impact), etc.
