Should we be careful for zugos (eating or drinking an even number of foods) today?
Although I initially thought we were not careful for zugos based on the fact the Beis Yosef OC (170:7) questions the Tur (170) for bringing zugos and the Shulchan Aruch doesn't mention anything, the Aruch Hashulchan YD (116:17) writes
ובזמנינו לא שמענו מקפידים בזוגות רק אם יש מקפידים יתנהגו כמ"ש
Nowadays we haven't heard people are strict for zugos, but if there are [people] who are careful...
