I'm 57 and have 10 years until I can retire, due to a layoff that wrecked my 401(K) and a divorce that stripped me of accumulated equity. Watching other folks retire earlier than me doesn't bother me, though. I'm at top of my professional career and loving my work, and I've got an awesome hardworking sweetheart of a girlfriend who loves to boondock travel with me. The things she pesters me about are for my own good - drink less beer, organize the garage and gun room, walk more, eat better, etc.. And always reminding me that we're living the best part of our lives.
Sure, I'm looking forward to not working but I'm not burnt out yet. However, the one lesson I've learned from watching other folks after they retire is this: if you retire to the couch, you won't be around much longer.
Find something to get you off your ass and out from in front of the TV. Go shooting. Go fishing. Grow a vegetable garden. Do the projects that you CAN physically handle. And for Pete's sake, let HER demonstrate the Kama Sutra positions that she wants to get you into. Likely will be more interesting than Ancient Aliens!

....and some rin up hill and down dale, knapping the chucky stanes to pieces wi' hammers, like sae mony road-makers run daft - they say it is to see how the warld was made!
