truly the 40s ae the best of life, finally the money, experience, & DGAFness to know what you want & to go after it + the health / energy to follow through
i think the U-shaped studies of happiness (claims that folks are happiest in childhood-and old age with a huge dip in middle age) are missing something
i mean, childhood was just hell, no doubt it's different for some but you have no freedom & it's random whether you get parents who are even decent people
