(And, yes, they’re already planning for my death. Haha.) What are some items that are heirloom quality that I should invest in for myself … and eventually my kids?J.R.Dear J.R.,I know you said this in jest, but I think it’s healthy for your kids to talk about and plan for your death, which, based on your description, I understand is not imminent. (Please note I said “plan for” and not “plot.”)Frankly, we’re seeing that younger generations don’t really have much sentimentality for family heirlooms like glossy cherrywood curio cabinets filled with collectible figurines. But maybe they’d love a well-insulated cooler, a Herman Miller Aeron chair, or a refillable leather planner to remember you by.Buying with longevity in mind is a great move, especially in this disposable-product-churn economy. And the kinds of high-quality things you’re describing are known as “buy it for life” (BIFL).There are some BIFL items that will still be beautiful and functional years beyond your lifetime, after which they’ll live on for someone else to appreciate—whether it’s your progeny, a friend, or an over-the-moon estate sale shopper. Here are some of my and my colleagues’ favorite heirloom-quality items.
