I am really sorry about your wife's situation. I read through some of your other posts so I am up to date on what has been happening. Like I said, I am really sorry. Just remember, you are going through this too so please try to take care of yourself.
Pivoting to your investment portfolio, I really like this setup. Especially because of the peace of mind angle.... Peace of mind is underrated and hard to value. (:
I think the World ETF in particular is a good move based on your objectives. You will get a lot more diversification than if you put it in something like S&P 500 Index. I may actually buy some of this world ETF myself so thank you for sharing.
One thing I think is interesting is the bond fund allocation you have right now. I prefer money markets right now but if interest rates drop you will end up doing better with the bond allocation.
Good luck with your wife's treatment and good luck with your portfolio!
