My mother-in-law has never invested

Hello everyone, I was talking to my mother-in-law recently. She is currently 50 years old, and she told me that she has never opened a 401(k), IRA, or any type of retirement savings account. She has basically never invested or saved specifically for retirement. I didn’t really know what to tell her because she kept saying that she feels like it’s too late for her to start. I was just wondering what people would normally tell someone in this situation. If someone is 50 and has never invested or saved for retirement, what would you say to them? Would you tell them to start with a 401(k), an IRA, or just start putting whatever they can afford into savings and go from there?
