I bet you wouldn't, at least not until your 70s. Here's my anecdote-based argument to the contrary: every single recent retiree I know (having $basicIncome as a pension) has taken 6-12 months off work and then started working again (where they are physically capable of doing so). The reasons vary from necessity, boredom or wanting to feel "useful". This seems to drop off sharply the mid-70s. I'm not saying that working is hardwired in humans, but it seems to be a strong part of our sense of self-worth.
