I'm going to share something quite personal with you. About 5 weeks ago I had a cardiac arrest just outside of a park in Newbury. I was given CPR immediately and very luckily by a passer by and I believe I was "dead" for about 35 minutes until the fifth shock from a paramedic's defibrillator revived me. I then spent 6 days in a coma in Basingstoke and now have an implanted defibrillator in case it happens again.
History wise, I had a heart attack at 45 but have run 20 miles a week since then, walk, cycle etc and eat healthily.
Today's my 57th birthday and I'm a pretty lucky bloke to be here. Only 8 out of 100 survive a Cardiac Arrest out of hospital.
I'm making a fantastic recovery & thanks to brilliant CPR the oxygen flowed through my body for that 1/2 hour so no after effects at all. No organ damage.
Worth watching the video if you don't know how to do it. One day you might save someone's life.
