3 years, 3 months.
Thanks to multiple family members taking DNA tests, it is officially undeniable that you have a decent amount of DNA that is Italian, Mexican (Native American/Spanish), Sephardic Jewish, and West Asian (from Iran, Iran, Lebanon). But I don’t think most people would think that if they saw you, thanks to your blonde hair and blue eyes.
Your physical traits are more representative of the Norwegian and British DNA you also have.
While your brother was also born with blonde hair, blue eyes, and fair skin, his hair and skin have turned much darker over the years.
I am beginning to have serious doubts that your skin will get much darker because by the time your brother was your age now, he wasn’t still getting sunburned as quickly and easily as you do.
This has been a summer of sunblock and sunburn for you.
You are the white sheep of the family.
