\begin{abstract}
Hi, Reddit! I argue that current efforts to reduce brain injuries in
youth tackle football---whether through adult supervision, training, or
new helmet designs---are largely not supported by scientific evidence,
and are therefore insufficient to protect players. Instead, to
significantly reduce the risk of concussive trauma, football
organizations should consider changes to the way youth football is
played---specifically, eliminating tackling, in favor of touch and flag
versions of the game. Read my article that I co-authored with Daniel
Goldberg of East Carolina University in the Journal of Law, Medicine and
Ethics
(http://aslme.org/pdfs/aslme\_jlme-42-3\_bachnyski\_goldberg.pdf). I
will post a link to a second journal article as soon as it is published
on Feb. 4. I'll be back at 1 pm et (10 am PT, 6 pm UTC) to answer your
questions, ask me anything! EDIT: Here is a link to a Perspective
article I wrote in this week's New England Journal of Medicine:
http://www.nejm.org/doi/full/10.1056/NEJMp1513993 EDIT: Hi Reddit! I'm
arriving and I'll start answering in a few minutes. Thank you for all
the great questions! EDIT: Thank you so much for all your fantastic
questions. It was really a privilege to have so many people engage with
this topic and share their thoughts. I have to leave now to get back to
my dissertation (which I'm supposed to defend in April!). Thank you
again.%
