Fitness and lack of it.

[Prepper1]

Too much of anything is bad for you.
Look at the marathon runners who compete regularly, lots develop Heart Arrhythmia http://www.active.com/running/Articles/M...rathon.htm
I used to know a guy fit as fuck, went running 5 miles every day in his work dinner hour.
Dropped dead with a heart attack.
Humans are meant to be active yet not overly so, over train at your peril.
finding the balance is I suppose an individual thing, but don't become obsessed, then exercise becomes an addiction that only death can satisfy.
My dad for example played football EVERY Saturday without fail for the village team, no heart problems in the family and he died of a heart attack at 52.
I have an allotment, so work fairly hard there digging and such, I cycle there, I cycle other places and school holidays Me and my boys go scouting bols on the moors and such.
In my opinion exercise or I should say its overuse should carry a health warning.
