Personality change. Mentally-This is going to be the hardest part of change, because when people do change their personality it's hard for them to stick to it. Don't think it's fake because you want to improve yourself. There is no harm in becoming a better person, just as long as you do the right thing.
Widows or widowers benefits based on age can start any time between age 60 and full retirement age as a survivor. If the benefits start at an earlier age, they are reduced a fraction of a percent for each month before full retirement age. If a person receives widow's or widower's benefits, and will qualify for a retirement benefit that's more than their survivors benefit, they can switch to their own retirement benefit as early as age 62 or as late as age 70.
Qualifying Widower is a filing status that allows you to retain the benefits of the Married Filing Jointly status for two years after the year of your spouse's death. You must have a dependent child in order to file as a Qualifying Widower. In fact, the full name of this filing status is actually Qualifying Widow(er) with a Dependent Child.
