Do you eat by kideishim?
Big time.
They say from reb Yaakov that the reason why there is a minhag to make a lechaim etc on a yhourtzit is because originally the minhag was to fast on a yhourtzeit, when that became to difficult they made a siyum and a lechayim for the siyum, now we are left with just the lechaim.
Point is that yidden like making lechayims, any excuse if fine by me.
