"I think maybe when you live with someone who is really very ill for a long time, it somehow gives you more of a greedy appetite for life and maybe, yes, you are less measured in your behaviour than you would otherwise be"

In the quote by Nigella Lawson, she reviews the transformative impact of coping with a person suffering from long-lasting disease. This experience, she recommends, imparts in an individual an increased appreciation for life, which she refers to as "a greedy appetite for life". The word "greedy" here does not bring its conventional unfavorable connotation but rather conveys an extreme desire to seize life's opportunities and moments with higher seriousness and enthusiasm. This shift in perspective can be seen as a response to living in close distance to the fragility and impermanence of life, which long-lasting disease starkly highlights.

Lawson also explains that this transformed outlook may lead to being "less determined in your behaviour". This recommends a possible departure from traditional restraints or societal norms in favor of a more spontaneous mode of living. The recognition of life's brevity and unpredictability might trigger people to pursue experiences and relationships with less reservation, prioritizing credibility and fulfillment over caution and consideration.

Hence, this point of view motivates accepting life's uncertainties and relishing its minutes, rather than adhering strictly to regular or societal expectations. By referencing the effect of "dealing with somebody who is actually extremely ill", Lawson also discuss the psychological intricacy and strength needed in caregiving scenarios. The daily confrontation with disease and potential loss could act as powerful drivers for re-evaluating top priorities and habits.

Overall, Lawson's words highlight a profound philosophical reflection: the existence of illness in one's life, while challenging, may precipitate a smarter, more ravenous engagement with life. It talks to the human capacity to adapt and discover charm and meaning in challenge, transforming difficulty into a deeper, more pleased experience of living.
