Pls. suggest some good Malayalam books that I could gift sr. citizens to take their attn. away from phones!

Hello. Some of the sr. citizens in my family are addicted to their phones all day long, so I am thinking of getting some Malayalam books that they could get hooked on to. So, please suggest some good Malayalam books that sr. citizens would like. The topics are varied - from humour to history about Kerala to cook books to astrology to whatever you think they could like. I heard that the actor Innocent's book about his cancer struggle is a good read. Are there any books like that? Please do comment with the Amazon/flipkart links, so that I can order them right away.
