My wife is not prone to anxiety (a medical condition)... although she can be a bit of a worrier. We have discussed the dangers involved with cycling. I explained the low risk-serious consequences.... I don't think she fully grasped the idea. So then.... I reminded her I will most certainly die.
Because of my age... the odds of my passing in the next few years are really pretty good. Since most people do understand that death is inevitable that may be a good place to start. Lots of military, police, fire fighters face much greater risks... no matter how they get to work. Once people pause long enough to remember that life is temporary.... making the most of the brief time each of us have makes good sense.
The old saying about the reason we pray before meals.... is because it is to remind us that we are mere mortals. We must practice many ritual routines like eating and sleeping.... just to stay alive. Tell your loved ones that you are doing all the stuff you need to do to stay alive.... and enjoy your life.
