Lobsters don't slow down, weaken or lose fertility the way most animals do with age
Unlike humans, lobsters keep growing, keep reproducing and show no measurable decline in strength as they age, a pattern gerontologists call 'negligible senescence,' linked to an enzyme called telomerase staying active throughout their lives. They aren't immortal — they still die from the physical strain of moulting, disease, predation or being caught — but ageing itself doesn't seem to be what kills them.
