"When We're Older" by James Blake speaks to the strength of a deep and enduring connection between two individuals. The song embraces the idea that no matter what challenges or apocalyptic events may arise, their bond remains unyielding.

In the first verse, the lyrics express that even in the face of impending disasters, such as storms, burning up, or depletion of resources, the presence of the other person gives the singer hope to believe in a better future. This suggests that their relationship provides solace and a reason to hold on.

The second verse continues this sentiment, mentioning the possibility of everything coming to an end or catastrophe striking. However, the singer assures their loved one that they will be together even if the sky falls and fire consumes the world. This illustrates their unwavering commitment to each other, no matter the circumstances.

The third verse uses natural disasters as a metaphor for life's tumultuous moments. Just as an earthquake shakes the earth, the singer acknowledges that life can be tumultuous and unpredictable. But in those moments, they affirm that their loved one is the first person they would seek for solace and comfort.

The final verse explores a different aspect of the relationship, looking toward the future. It suggests that when the time comes for them to leave Earth behind, possibly through death or some other transition, the singer hopes their departure aligns with their loved one's. This desire implies a wish for their connection to remain unbroken, even beyond earthly existence.

Overall, "When We're Older" conveys the idea of a love so profound that it transcends adversity and endures through any circumstance, whether in moments of crisis or in the face of mortality. It speaks to the power of a deep and everlasting bond between two individuals.
