I think more than anything this is what will ultimately delay our retirement until the "proper" age of 65 or so. We don't want to wait until retirement to see the world and have time to enjoy our hobbies because the littlest thing can change that plan. Either of us could get sick or die, or there could be another recession just before our retirement age or there could be some other change that delays us until we are just simply too old and infirm to do it. I'm not saying our outlook is "do all the things today!" but we definitely put more towards experiences and vacations than Suzy or Mr Mustache would probably deem prudent at this point in our life (after we meet our employer matching of course - we DO at least pay ourselves first for that "free" money!)
While we are shooting for age 60, this frames our expectations as well. DH and each have a parent who has died. DFIL died at 58. My in-laws had just gotten their youngest child through undergrad and had paid off their mortgage early. They were looking at the trip of a lifetime to Italy and him retiring in a year or 2. Instead, he died suddenly of a heart arrhythmia.
My DM retired early from her librarian job at 56. My DF retired from his manual labor job 2 years later at 66. Their house was paid off, and they had decent pensions/retirement savings. They enjoyed doing stuff together and spending time with their children and grandchildren. Then my mom died very quickly from metastatic endometrial cancer at age 66.
While we don't "do everything today" either, there is no doubt that what happened to our respective parents has colored our outlook. It is part of the reason we own DVC and that we are financing it. Suze and Dave R and the rest would say to not own it at all or save up and pay cash, etc.
Now, we're not total spendthrifts. We are still in our starter home, and we have refinanced twice to only lower the interest rate and shorten the term and not take out any equity. As it stands now, the house we be paid off when we are 55. By 60, we will have had 5 additional years to save, be mortgage and all other debt free, and have our 2 kids finished with undergrad. If healthcare is sorted out by then (over 15 years from now, so maybe?

), we should be on track.
