<prompt> Human: Opened mine at 18; put in 2.5k, but then mostly ignored it until I was 23. So I missed out on investing in 09. Doh.What about you all? Im asking because this is probably the most financially responsible subreddit, and Im trying to make myself feel better about the fact that my 26 year old boyfriend doesnt have any retirement savings yet.  <response>: I opened my IRA yesterday. I am 25.
