I don't know, most that jump are 4 or 5 stories up it seems and are likely in shock or possibly inebriated. 
 
When we skydive we free fall for quite a while with confidence the chute will open. 

It used to be an 'in' joke in skydiving circles.

If you are married to a thai woman, or thinking about it, you should be preparing for your death. Never ever let the woman know your net worth. Convince her that you are receiving a pension every month that stops when you die. And buy the condo in your name, naming your children or someone ba k home as the beneficiary.
This is the beat way not to "accidentally" fall from your balcony.

Yes, and a great way to leave your wife nothing when you die. Way to go. If you are THAT paranoid you will be murdered by your wife, you ought not be married and need psychological help. I'm rather sure 99.9999% of Thai wives don't plan to murder their farang husbands. Sheesh!
