I'm in my late 40s now, and loving it. But the peak year for me so far was 34. That was the year I left my abusive husbandof 13 years, took my kids and started a new life for us. I felt empowered, sexy, free, and, finally!, safe and at peace.
However, since then I've remarried and made more changes, learned more lessons, gained depth and become more grounded. I'm thinking that in another ten or 15 years, 48 will prove to be a peak year!
