Seven people died this morning over Texas. There is already so much wailing and gnashing of teeth and making of little 'In Memoriam' gifs and people remembering where they were when they heard the news that I felt some perspective was needed.
My point? Other than this being a big explosion you can see on TV, this is no different from all of those other people who die today. Whether they have their heads halfway through a windshield, a sucking chest wound from a stray bullet or are spread across Palestine, Texas, some humans died and we should show them the respect they deserve for attaining that state. Nothing more.
And a lot of those that are crying about this don't even support the space program.
I have found it helpful to do the stretching exercises my physical therapist recommends. Do some core strengthening exercises, such as the ones highlighted at The Mayo Clinic. By keeping your core strong, your back won't put itself in a position to cause that sciatica pain you are having.
