The Army did a super great job of training me in a lot of first aid and obviously focus a lot on heat and cold injuries as well as proper CPR
There have been--- in my late in life modeling hobby--- a few occasions where I saw the initial signs of heat stroke/exhaustion, or heart attack and I became "First Responder"
Of course the Para Medics, once arrived, did their thing with the right training and equipment....but I like to think that my early observation and action helped save my friend
I think I will get one of these Apps...not so much for me or my retired Army wife...but for my son who helps me fly some weekends and does NOT have this training...
I am smart enough to Not play in the cold....but Texas heat, too much fun, not enough shade or water...can combine to be dangerous
I believe for us older guys having someone who can recognize Stroke or Heart attack is a good idea
In our smallish community, recently some of our brothers had these issues and thankfully are still with us
