If you are always losing your keys in the morning or walking out of the house without your mobile phone, sleep deprivation could be to blame.

Temporary mental lapses are now believed to occur when these cells struggle to translate visual information into conscious thought.
It means if a bunch of keys are in front of someone, they could walk past without picking them up.
