Time, we know, is relative. You can travel light years through the stars and back, and if you do it at the speed of light then, when you return, you may have aged mere seconds while your twin brother or sister will have aged twenty, thirty, forty or however many years it is, depending on how far you traveled. This will come to you as a profound shock, particularly if you didnt know you had a twin brother or sister.
'Protect me from knowing what I don't need to know. Protect me from even knowing what I don't need to know. Protect me from knowing there are things to know that I don't know. Protect me from knowing that I decided not to know about the things that I decided not to know about them. Amen' That's it. It's what you pray silently inside yourself anyway, so you might as well have it out in the open. 'Lord, Lord, Lord. Protect me from the consequences of the above prayer. Amen.' And that's it. Most of the trouble people get into in life comes from leaving out that last part.
