I caution for you to be careful not to look at this through rose colored, king of the hill glasses. Mid 40s, so I would assume your salary to be well over six figures? Maybe approaching the 3/4 of a million mark? That's a very easy place to sit and say things look great. By corporate standards at some point you'll max out your usefulness due to old age, health issues, and it will make sense to replace you with someone who is younger, costs less, works longer hours, and fits more with the culture. I genuinely hope this never happens, as it would be both unethical, and illegal, but that's the Silicon Valley of today.
