Retirement - looking for savings ideas

Retired almost two years ago. I didn't start 30 years ago, as Rusty suggested, but the last ten, I worked pretty diligently towards it. As I paid off debt, I increased my 401K contribution. The last 5 years I was putting in 25% of my pay. That went into an investment account, that hasn't been touched, other than to add to. Also worked for an ESOP. (employee owned company) The stock from that is still sitting there, and growing. I did buy a new truck after I retired, but paid cash for it. I've worked a little part time, and done some odd jobs for extra spending money. For the most part, I can live on my Social Security. Only bills I have, are the ones that you never get rid of. Taxes, insurance, utilities, etc. I am an easy keeper.
