SB 1.8 - Lifespan in Kali reduced considerably

Duryodhana and his party cunningly usurped the kingdom of Yudhiṣṭhira, who had no enemy. By the grace of the Lord, the recovery was executed, and the kings who joined with Duryodhana were killed by Him. Others also died, their duration of life having decreased for their rough handling (sparśa) of the hair (kaca) of Draupadī. Before the advent of Kali yuga, the brāhmaṇas, the cows, the women, the children and the old men were given proper protection. The protection of the brāhmaṇas maintains varṇāśrama, which helps in spiritual progress. The protection of cows maintains the nutritious milk, which helps the brain to understand spiritual life. The protection of women maintains the chastity of society, by which there will be peace, tranquility and progress of life. The protection of children gives the human form of life its best chance to prepare the way of liberty from material bondage. The protection of old men gives them a chance to prepare themselves for better life after death. Even by insulting them one’s duration of life is reduced. Thus in the age of Kali, the life duration is shortened considerably. Duḥśāsana insulted Draupadī, and thus the miscreants died untimely.
