Aside from the fact that I unfortunately developed ALS, I have been fortunate in almost every other respect.
Literal
Unfortunately ALS [at-に] caught-completely thing [topic-は] separately, I [topic-は], other almost all points [at-で] fortunate was.
A sentence attributable to Stephen Hawking. ~にかかってしまったことは別として = 'setting aside the fact that I contracted.' ALS in katakana-style abbreviation. ほとんどすべての点で幸運であった = 'was fortunate in almost all respects.' A profound statement about perspective.
