Warning: Extremely Crazy/Geeky Thoughts!
I couldn’t help but noticed how my friends and colleges tend to automatically pair up around college. Pairing up makes it easier for students to recover from missing lectures, solve homework, etc… because your friend serves as your backup. Kind of like a RAID-1 array.
In a more generalized sense, marriage should be a RAID array for everything in life, no? Your backup for going against the world. Mathematically speaking, your failure rate is 0.0004%.
But one of the most redundant configurations is RAID-6 which, according to my analogy, means having 4 wives! XD
With Raid 6, the system can tolerate two concurrent disk failures, or in human sense, two people can become ill and things would still be moving along as normal.
But then there’s internal disputes that are unaccounted for… meh, so much for security. :P
