Jobs I can do to avoid physical labour in a post-apocalyptic world:

• Clothing production (knitting, sewing)
• Silversmith
• Welder (probably)
• Food production (cooking)
• Urban planner (based on transferrable skills)
• Carpenter
• Underwater scavenger (SCUBA gear accessibility required)
• 21st century popular culture historian (expertise in sci-fi and comedies)
