Navel.

Imagine if the human belly button were located not on the stomach, but on the back. It seems an absurd idea—almost comical. Yet, this thought experiment yields surprising insights, especially from an economic perspective. A dorsal belly button could have far-reaching implications for industries, labor efficiency, fashion, healthcare, and even ergonomics.

Let's start with maternity care. A dorsal umbilicus implies that the connection to the umbilical cord is located at the baby's back. This could force midwives to adopt innovative birthing positions, leading to the development of new equipment and techniques. It may seem more expensive at first, but as with any technological shift, it opens up a market for new instruments, training, and medical expertise—all sources of employment and economic growth.

Next, the apparel industry. Clothing designs would change drastically: crop tops with back openings, jeans with cutouts in the back, and a whole new category of back-inspired accessories. Fashion houses would benefit from the need to completely redesign collections. Innovation and product renewal would drive higher sales figures, which would boost the textile sector. Fast-fashion chains could launch new back-focused trends each season.

The personal care industry would also benefit economically. Navel care products—think ointments, cleaning products, or jewelry—would focus on a hard-to-reach area. This means brushes with extension handles, mirrors with navigation aids, electronic assistants, and expensive back treatments in spas. The wellness sector would grow, simply because the dorsal navel requires more maintenance than the abdominal navel.

A less obvious, but interesting economic impact lies in work posture and ergonomics. Consider people who work sedentary jobs. With a navel-shaped back, additional demands would be placed on chairs, backrests, and ventilation to prevent skin irritation or overheating around the navel. This would force office chair designers and manufacturers to develop innovative models – another boost for employment and revenue.

Even the carrying capacity of babies would change. Babies with a dorsal umbilicus would have to be carried differently, perhaps more often on their stomachs or on their backs with umbilical support. This means new baby carriers, adjustments to child health clinics, and revised guidelines for parents. The childcare and baby products sector would flourish due to this new demand.

Finally, pop culture. Think of what this would mean for art, music videos, body art, or advertising. The aesthetics of the body would change. The "navel on the back" could symbolize something new—rebellious, futuristic, or spiritual. Cultural and artistic industries would embrace and capitalize on this shift.

While the idea of a dorsal belly button remains absurd, it's clear that even a small change in human anatomy can have major economic consequences. The power of this idea lies not in its feasibility, but in the creative stimulus it offers designers, entrepreneurs, and thinkers. Sometimes economic progress can be found in the most unexpected places—even right in your back.
