Investment in Gold

I normally save my money in Bank account. I know that it's better to do some investment rather than put in the bank saving or fixed deposit to get higher returns.
For me, I not dare to try investment in Share Market. It's a bit high risk.
Unit Trust investment will be medium to long terms investment. I heard that the returns are much better than FD and it is a bit secure.
I have not becomes the level to do investment in property. That's really need huge excess money to go for it. I prefer to be self finance rather than liabilities on hand.
Gold investment sounds new for me. Maybe I would consider this when I have excess money.
