In the quote provided, the speaker refers to themselves as a person who has a deep-seated preference for sandwiches. They suggest that this preference is so ingrained that it might be linked to their genetic predispositions or early-life experiences, which they metaphorically describe as "epigenetic switches." This indicates an enduring and unchanging fondness for sandwiches over many years.
The deeper meaning of the quote revolves around the idea of personal preferences and habits becoming a fundamental part of one's identity. The speaker humorously implies that their love for sandwiches is not just a fleeting preference but something deeply rooted in their personality, possibly shaped by early experiences or genetics. Furthermore, they point out a practical reason behind this preference: sandwiches are convenient to eat while engaging in other activities like reading. This adds an element of pragmatism to the statement, suggesting that personal preferences can also serve functional purposes in daily life.
