37 isn’t around 40 because it’s 3 full units away, placing it firmly in the mid-30s. "Around 40" typically refers to numbers like 39 or 41within 1 or 2 units. Plus, 40 marks a new decade, while 37 still belongs to the 30s. The gap is small numerically, but meaningful contextually.
it's not that serious.
