Tbf he did say expensive lifestyle. Which is why I asked what that means because as we all know one person's expensive is another's spare change.And this is why people work until they drop, thinking they need that much
How much you need is completely dependent on lifestyle. I have nothing like that amount and stopped work two years ago, in my 50's. Saying that, £1.5-2m isn't going to go very far if he spends half a million a year so you can't give a figure unless he does.
