Is there anything he has been meaning to do but hasn’t gotten around to? Organizing a stamp collection, putting together a family album, researching ancestry? Anything he hasn’t had the time to do until now? Does he like puzzles? Crosswords, sudoku? Does he have/want a pet? I know his condition is only temporary (thank goodness) but a pet could help him during the transitional period and remain a close buddy even post-recovery.
