.....because the very essence of life is risk it is what makes us unique! We all make a risk assement in everything we do. A risk that is acceptable to one person may not be to another.
What are we to do if we are unprepared to take risk, lie in bed and wait to die? Of course there is a risk that you will get bed sores!
I fly over water all the time, I wear a lifejacket and take a life raft. For really long trips I fly the twin. I accept the level of risk associated with this, it is my choice.
I also stand up when I pee despite the risk that I may slip on the wet tiles, hit my head and brain myself!
Each to there own.
