Everyone has a different attitude about asset allocation. I'd say leave yours alone and figure out what your total expenditures (budget) will be in retirement. If you will be going on Obamacare and keep your MAGI to less than $48,000 (I forget the exact no.), your healthcare premium could be very low. Look up what constitutes MAGI income- very important.
I'd say you are good to go with $1.9 based on your life style.
Thanks. I'll have to evaluate that MAGI prospect... thus far i'm over the limit. Of course, the healthcare options are subject to some troubling people in power but theoretically if we aren't screwed over by corrupt factions, the prospect of taking advantage of a lower premium looks reasonably good.
