Exclusively in writing and many other tasks. There will only be a few out there especially on here but if you are left handed come share. Me and a cousin are both left handed the only ones we know of in our families and we both had bouts of severe migraines starting around age 9 that seemed to only come during summer and got less and fewer as we grew up.The migraines that would come every year during the summer started to go away as we went through our late teen years. We are both different ages btw, I'm 5 years younger. I wasnt told about this though until after I had a bout of it at a family function and my aunt told me that he (my cousin) also had migraines and that he had stopped having them regularly. And it wasnt until over a decade later that I even found out that he was also left handed. We werent close cousins obviously. But it always stuck with me. And another weird coincidence is there were two brothers at my school who also would have migraines and they both were also left handed.
