computer battery
some computers, have two of them
then tech comes, and, suggests you only replace
one of them, i suppose, so, a few weeks/or months later
he can come again, and, charge you twice
it is when you have complete days missing...
that is when i get concerned
or, you try to come back to your body
in the middle of the night,
and, you can NOT get in,
cause something else is in there
