This is really what I was trying to get at. I've pinched pennies my entire life and had a ton of luck with investing. I've delayed getting knee replacements for 11 years now because I didn't want the financial expense and didn't want to miss time at work and miss my chance to impress someone for the next promotion. I've always enjoyed high levels of stress since my work adds a lot however now that you add in having young kids and being so tight on money, my health is starting to sacrifice and I'm not combatting the stressful by doing things that I enjoy in life as much as I should. My dad retired 3 years ago at age 62 and he seems pretty miserable in retirement. His knees were just replaced, he had to have an ankle fused, and he needs to get his hip replaced once his knees recover. On top of that he has high blood pressure and is diabetic and had quadruple bypass open heart surgery 20 years ago. He has way more money than he needs in retirement and will eventually pass away without barely tapping into his balance. I don't want my story to be like my dads.
My general observation is that people have 4 stages of slowing down:
Mid-50s to Mid-60s - Still going well but starting to have some physical limitations. This is probably the best time to knock things off your bucket list and take long trips overseas. Of course, most people need to still be working throughout this stage.
Mid-60s to Early/Mid-70s - Starting to slow down more but still generally active enough to enjoy some retirement trips and activities. This is when you need to do all those things you said you would do when you were retired.
Mid-70s to Early/Mid-80s - A more sudden slow down, both physically and mentally. I've seen it in 6-7 different relatives so far. The trips and physical/mental excursions really slow down. Lots of hanging around the house, still seeing friends, rocking chair on the porch time. Not that many health issues yet but they are starting to pop up.
Mid-80s to Death - Less movement, more likely to need care in the home or move to a nursing home, not a lot of fun in general. If you make it to your Mid-80s you have led a nice, long life, IMO.
In terms of money needed, I think it's a U-shaped curve. You want to do lots of travel and bucket list stuff early on so you need money for that, on top of normal living expenses. Not much health care spending yet.
Then in the 70s-80s, you are some more health care needs but much less leisure spending as the trips and excursions slow down.
Finally by the mid-80s, health care costs go way up and that's the main component of your spending.
My plan and advice to others is to enjoy that first part of retirement and do the things you want to do. I feel like people get too worried about the health care costs in their 80s and save more money that needed so that they never got that trip to Australia or cruise around the world or whatever. When you're lying in a nursing home at 86 as someone changes your bed pan, you'll wish you took those trips and not that you could be in a nursing home with gold plated bed pans.
