Of course, everyone is. Anyone that denies it is either lying or doesn't realize it.

Does it affect my day-to-day life? NO. I don't think about it, ever.

All of you, wait until you are older, with a family, kids and a wife. A life, built throughout the entirety of your life, and tell me you don't fear losing it all. Tell me you don't mind NOT waking up next morning to this. Tell me you don't mind it just "ending".. Tell me you don't mind leaving all your loved ones that depend on your support behind.. Tell me you don't mind becoming lifeless matter in a coffin..
