I'm putting the max allowed in my retirement accounts, and it's invested fairly conservatively in index funds. I lost a bunch of money in the tech stock crash in the early 2000s, which makes me hesitant to dump more money in the stock market. I own an apartment and don't really want more exposure to real estate, either. I'm starting to build up enough cash that I don't want to just leave it in my savings account. The only debt I have is my mortgage, and while I have decreased the balance on it, the interest rate is so low that it seems like there must be something better I can do with the cash. Any suggestions? Kira, Washington DC

I don't have a question, just a comment on how our finances work. My wife and I agreed a long time ago we each need an allowance. We decided to take a percentage of our gross income as an allowance deposited to our personal checking account. The balance goes to the Joint account for all household bills and expenses. … This has worked well for us as we agree that most household expenses are joint. Gary, Milwaukee, WI
