I would suggest an annuity if OP is planning on living for a very long time and the money was completely unexpected. An extra $1000 a month guaranteed is pretty compelling. Sure you could maybe make $2000 a month from mutual funds or something, but it wouldn't be a stress free, steady rate of payments. It would boom and bust with market cycles
