Unfortunately all humans are born with weak immune systems, and sadly babies aren't fully vaccinated until they are ~2 years old. We protect them, because they eventually become our society. That pesky "future generations" concept.

You see, our immune system is built up over time with exposure to viruses, and inoculations. Then as we age, as our health decreases, our immune system gets worse again.

Personally, as I make my way through middle age, I hope that when I do reach my golden years I'm met with a little bit more compassion than "who cares about you, you're old and useless."
