I certainly do not have an answer to your question. But here are a few things that are worth taking into account.
If you are currently spending $100,000 per year, the odds are that you will have to spend more than that amount annually to maintain your current standard of living for the next forty years.
If you live to 100, it's very possible that your expenses could significantly increase if it becomes increasingly difficult to do things that you can now do on you own. And that's not just a concern for what happens if you move to an assisted living or other facility. Even if you're in good shape at age 95, you may need a certain amount of assistance to manage daily chores.
There are numerous online calculators where you can plug in different scenarios re your assets, your non-investment income, your expenses, rate of return, etc. and see what happens. I'd suggest you use more than one calculator -- when I played around with them, I got very different results.
