Ya. In your 40s should focus more on health and well being. Whatever robust dreams in your younger years are either fulfilled or still dreaming away but must be realistic.

I am in my mid 40s, though currently still employed but more relaxed and not so worried about retrenchment cos no commitment, no debts no kids even though I am married.

The last thing you worry is get into medical debt so take care of your health really. One health bill can wipe out more than half of your savings.
