Claimant's regular work was common labor. Before March 27, 1950, he was suffering from hypertension, high blood pressure and cerebral arteriosclerosis. On March 27th he was working as a pick and shovel laborer digging a trench. The ground was hard; the work was arduous; but it was his usual work. While doing this he suffered a cerebral hemorrhage. There is medical opinion that with claimant's physical background the work he was doing was a contributing cause to the hemorrhage. Where there is such a background of physical weakness even the ordinary work which helps to cause disaster can bring about an "accident" in the sense in which the word is used in the statute. ( Matter of Kayser v. Erie Co. Highway Dept., 276 App. Div. 789.) Decision and award unanimously affirmed, with costs to the Workmen's Compensation Board.
