That depends on a ton of factors such as:
- financial situation
- health situation
- pension details
- family situation (some pensions roll over to spouse, some don't)
Don't keep working if you don't need to, and don't take your pension until you actually need the money. When you should retire has less to do with your pension and more to do with the other stuff above.
Also, consider taking the pension in a lump sum, sometimes that's the better option. But do your research and strongly consider talking to a fee-only advisor, since they'll know what to look for.
