“Charaidim all over the world are in Shidduchim by age 20-21. (Europe & Erets Yisroel by age 20. Followers of the Chazoin Ish, and Chasidim all over the world at age 18.”
Nice try. At age 27 and three months, the Chazon Ish married a much older woman whom he knew could not bear him children. They remained married till she passed away. He did not remarry.
