This question could be very useful for many FA patients, and also for their family, friends and employers.
In my personal opinion, any work that requires a lot of phisycal activity is not suitable for FA'ers .
Even if they are young and they are only slightly affected and could do almost any movement, they should consider office works, especially work that can be done from the computer, that will not require their physical presence in the work field.
For example, I run an e-commerce website (which is getting harder to handle, because of stocks, but doing business on marketplaces is a very good alternative) , do web developing, president-founder of "Asociatia pentru Friedreich" ( which is an association for Friedreich's Ataxia in Romania).
