I also didn't lose any money in the 2008 crash...in fact took a distribution with profit (not loss) from one of my funds. My average annual returns have been around 14% give or take, with one year since being at 24+%. It's never too late to start investing IMHO but choose investments that have a track record of doing well over 5 and even 10 years. Right now I'm favoring exchange traded funds (ETFs) for my new investments because each holds a bundle of companies like mutual funds but trade like stocks in that you don't have to buy any particular dollar amount of shares at once and you can see real time share price quotes throughout the day. I also favor Schwab as a brokerage because many of the funds, ETFs are on their list of fee free trades. I also find their website to be very user friendly, including their "research" feature that gives detailed rundowns on each fund or ETF by rating, returns, holdings, etc. I hope you and your husband can see your way to getting started and have much success.
Regarding your reply about checks and cash...I believe checks are all but obsolete, what with credit and debit cards being so handy. Most months, I only write one check a month and that's for our carrying charges (co-op speak for HOA fees). If the managing agent ever installs a method by which we can pay be credit card, the only checks I would write would be to enclose in sympathy or birthday cards. My mother had a checking account but I don't remember how long she had it.
