lol what is retirement?
I just know that conventional advice is to split your money more towards riskier investments earlier on in life, and slowly slide it more to safer investments as you age.

Depends on when you plan to retire. If it's greater than ten years, I would suggest putting 100% in the most aggressive fund and gradually diversify in less risky funds as you get closer. It's hard to really to give a more dedicated response without knowing what the portfolio's are in each fund. I'm only a CPA though so I may not be the best source, but it would also would be nice to know the tax status on the funds you're contributing as well.
edit: Is this an IRA/401(K) or something else?
Something you do when your life's work is unfulfilling like being a corporate drone a la me.
He won't retire. He will be injecting a gorillion Hamm's into his veins and snorting lines of coke off scratched up Thin Lizzy LPs until he dies of heart disease at 47.
