I'm banging out on the 5 year exto (if I get it). I would be shocked to see it last more than two years though - either the company is going to be full steam ahead or bankrupt by then.
No plans other than family time, travel, and make memories for a lifetime. I was planning on being out in my early 60s, going out now for a couple years may extend that to 65, but this is a once in a lifetime chance to take a mid-life sabbatical and still be financially secure. I would not be able to do this without mil retirement though.
