Whether you wish to live longer than your husband or not it shows that you love him very much. If you wish him to live longer it means you need him very much. If you wish to live longer it shows that you care for him very much.
I have heard of this before . I think women live longer than men it is because that women usually share their mood with others .And they cry when they are very sad .But men always hide their feelings .They still smile even if they are not happy . This is bad for their health .
