I’m meanwhile 56 years old and my husband is 65. We created these embryos in 2012.
I’m mechanical engineer, 1,79 m tall, 62 kg so quite slim but good muscle due to my work, blonde and blue eyes. I was born and raised in Munich, my parents fled from the eastern parts of Germany.

I like to hike, swim, work, astronomy and rock concerts.
