In this crisis Why can't some people follow the advice to look after themselves and their own families ?

Many elderly people have the same sort of attitude. It's both understandable to an extent and frustrating.

They think that they might die soon anyway so why bother being miserable for a few months when they only have a short time left.

They only think of the issue as whether they will GET the virus, and never about the chance that they might PASS it on.

I think everyone over 70 should be tested and if clear, should be sent on a cruise for 3 months. Keep them all together and out at sea until this blows over.

Yes I agree entirely with U , your wife should stay home to keep both of U safe from the virus. If she goes to these selfish people than she is just as selfish as them.

I have been extremely ill and had a massive operation which left me with a compromised immune system.  If I am in contact with anyone who has this virus I'd be very likely to get it also and my body will not be able to fight it.  I stay indoors, keep warm and eat healthily.  I take the medication I have had to take daily since the surgery and follow doctors' advice.  I can do no more - I neither want it nor do I wish to pass it on.  Everyone should feel that way and act safely and sensibly.  I am 77.

PUT YOUR FOOT DOWN. Tell her if she keeps on, you will move out. Then, do it.
She apparently doesn’t appreciate that she can pass the virus to THEM - and THEY are more likely to DIE.

This is why the Church of England was created so you can get a divorce so your life won’t be destroyed by some crazy bltch. Leave the hoe and go live out your days in the Bahamas, the weather there is good for your diabetes too.

Even MORE important is that your wife could catch the disease, and before she develops symptoms, SHE could be passing on the infection to those elderly people.
Your wife could be responsible for their deaths, without ever intending it.

We stay home no ONLY for ourselves, but also for the well-being of OTHERS.
And since you are a diabetic your wife could end up being responsible for infecting you.

Undoubtedly, she has invested in a self-image of her as a caring giving person .. and usually this is a GOOD trait.  But she needs to "reframe" her concept.  With this pandemic, it is no longer unselfish and caring to visit the elderly.  Help her see this, and hope that she has enough self-esteem that she doesn't need to continue this dangerous activity in order to feed self-image.

It is utterly selfish to become a "coronavirus Mary", spreading the infection around to others. If we TRULY care about others, we will safeguard from spreading an infection to others.
