47 year old guys have been known to drop dead from coronaries with no prior warning signs. Spending time outdoors in an area like the Gulf (although I have to say tomorrow’s reported high temp in Dubai will be a camel’s hair under 100F - cool for June) could be unhealthy for someone nearing the big “50” too.
60gunner posted a story about a 37-y/o in a similar situation. Title was “Famous Last Words”.
