to curb the doomscrolling (laptop is as bad as phone) , i gave my father a big old Lego box - a Volkswagen beetle (which stayed for years, assembled by my kids.. which don't play that anymore. So i disassembled it). He had never tried those. Took him a week to build it, rearranged the room, studied the book like plant-specs-long-time-ago.. Then i gave another one, of similar size ~1500 pieces. i have one more ready-to-give "set". And then i plan to give him the rest 40kg well-sorted-but-in crates Lego, and the heap of model-books ~100+ , and let him do whatever he wants.. hoping he'll start improvising one day. Though.. may need a new empty room :/
