Is Celine Dion nuts?

Seriously, she has a miscarriage, tries to get pregnant again & fails. And now she & her husband are trying artificial insemination. Not to mention, she already has a kid, she's 41, her husband is 67. Gee is it any wonder she had a miscarriage, then failed to get pregnant afterwards??? And if she wanted to have another child, why would she wait 8 years after having her first one? Why wouldn't she take a break for a few years after the birth of her son to try to have another kid?
