Yeah that all makes sense and I agree totally that I expect to do more travel when young then when old. But travel isn't the only expense, there is also health care, which operates in the inverse. And once I stop traveling I imagine I'd still love to live out my days in some waterfront property waking up every morning to the ocean, that won't be cheap. And if I had the money I'd rather have 24/7 in home health aid once needed rather than move to a retirement community, that will be expensive too.
Just not sure which side of the equation will win out, especially considering the trends of health care costs.
