Since when does medical science have the only say in the yeshiva world? Hashem can do anything He wants to proove to those of us that are toos imple to understand His great ways. So I still think if these people put their minds to it they can accomplish anything in the entire world.(even run in the olympics and win first prize) If you want it bad enough shoot for the top and with Hashem’s help you will succeed.
GOOD LUCK to all of those people that have dreams and willeach to their highest point and overcome thier habits (whatever they may be) and start living life in a way that YOU wll be proud of later.
