It's not just about the years spent in retirement, but what you're doing. This is something I heard from a financial advisor - Retirement happens in phases.
Go-go phase. Years spent in relatively good health. Add extra budget for travel or big-ticket items to enjoy, like an RV.
Slow-go phase. Staying close to home, maybe spending time with grandkids. Increased medical bills.
No-go phase. No travel, but largest medical bills.
According to the article linked by @JWBananas, lead is correct. Printers changed it to lede in order to avoid confusion with another tool called a lead in the printing context.
One thing nobody points out is that those last 5+ years of your life, your health will probably be failing, physically and maybe mentally. If someone has to take over your finances and they aren't financially literate, your money will run out a lot sooner.
I'm not talking about someone stealing your money(which does happen), but someone who means well, but just makes bad decisions. There's no easy fix for it, but a living will helps.
Nah, age has nothing to do with it. It's merely someone who has stopped working because they no longer need an income to support themselves for the rest of their life.
I would say someone who stopped working for their primary income. Some folks still work for the social aspect or to live a bit comfier. Typically I think those folks do far fewer hours though.
