It's amazing what the power of love can do.

Melvyn Amrine, of Little Rock, Arkansas, is battling Alzheimer's, but, as this video proves, it's not robbing him of the love he has for his wife. He recently went missing, only to be found determined to buy his wife flowers for Mother's Day -- something he's done every year since they had kids.

It just goes to show sometimes love really can conquer all.
