I was just pondering at long-lasting items when I saw the remnants of my gold necklace with an amber pendant. It was broken when my babies were really, well, babies. They would have that jerky arms while I'm breastfeeding. Their fist would catch the necklace and it would break in two. I bet a titanium sports necklace would have survived babies fist. I bet such a strong necklace would survive an angry baby's grab. I tried to fix my chain a couple of times, and the third time it broke, I just let it be. I would keep the necklace because it has such good memories for me, but it is not a strong necklace.
