All life has risks.
The risks in the western world are far lower than those in much of the rest due in no small part to the risks taken on by the military over the years in defending you.
There is currently a war going on that has been going on for longer than WW1 or WW2, and carries a very high risk to those servicemen involved.
If the small risks that you must run due to the military practising above you for that war upset you then may I suggest you pour yourself a large glass of man the F@$k up.
