Many people have zero fear of heights and aren’t anxious of sky jump in Vegas or sky diving bungee jumping or anything else. It’s not unusual. Your lack of reaction to Sky Jump is neither here nor there. How does one suppose to react? I am afraid of heights but many people I know can’t care less. It’s nit abnormal. When questioned, normal honest answer would be “no I don’t get anxious doing things like that”. I don’t think it’s a big deal or indication of some abnormality. I have zero fear of public speaking. I can speak in front if anyone about anything. Others get very anxious. I have no problem telling people that I am not anxious in these situations whatsoever. And I am not a psychopath. Lol

You don’t have to tell people that you are psychopath (if you really are, that is) but you can tell them that you don’t particularly feel certain things much.
