penguinsfan7,

There are a lot of things you have control over. Whether you develop CTE is not one of them. Evidence suggests genetics can play a part in who develops problems and who doesn't.

There are no weekly suicides of NFL players. This is your anxiety/OCD speaking. Those that have happened were spaced over years with a few clusters. Many of the brains being studied are from players who have lived long lives or died from other illnesses, cancer/heart disease, etc. Frank Gifford was 85 and his brain was wracked with CTE but is did not cause major problems until later in life.

I suggest you purpose to live a clean life. Minimal alcohol, good brain nutrition, limited stress, healthy friends (no high stress/maintenance friends), healthy thinking, healthy habits, safe activities, etc.

At your age, there is great promise they will gain understanding to treat those few who develop CTE. It has similarities to Alzheimer's Disease and they think treating it will be similar.

So, try to deal with your anxiety, hypochondria and OCD and your life will be much better.
