Investing on gold more than any other things

I have a friend who invest in gold more than any other things. She said that it’s one of her securities in life. So, whenever there will be a special occasion, her husband will not buy any other things except for gold in forms of jewelry, coins, gold bars, and the like.

As of now, she said that she has lots of collections yet she’s longing to collect more and more. For her, these gold investments that she is having are a good inheritance for her four kids. And I can’t blame her for that because gold’s value will always appreciate.
