Honestly it depends on context.
Financially right now at 48 I'm sitting really good, I'm stress free, and I'm basically coasting through life pretty damn happy. Ever since I hit my 40's my house has been paid off, I basically have very little bills and I'm just at a great point in life financially. I have total financial freedom and make good money for where I live.
But I have health issues that popped up in my late 30's that drag me down some. Physically I peaked into my late 20's. I definitely felt a change in my late 30's where I took a little longer to recover, got a little more worn out by some physical activities and what not.
Mentally I don't think anything is better than being a young kid like late Elementary and you just kind of have a blissful ignorance of the world in many aspects and my life consisted of just friends, doing activities, having fun, riding bikes, going swimming that sort of thing.
Not really a care in the world and no worries about anything that adults have. Not concerned about any finances, politics, things to take care or any health concerns. You just always feel on top of the world and the world seems good.
I'm looking forward to retirement and feel like that could be the best. My dad literally just retired the last day of April. Been retired like 3 weeks and seeing him kicking back where every day is "Saturday" just makes me want that all the more. I stopped over there before work this afternoon and he is just mowing the lawn with not a care in the world. Has been up to his cabin at the river like 3 times already in the last 3 weeks. He is living the good life now.
