I believe it is very difficult to go to Hell at any age!
Jesus seems to believe the exact opposite, that is it difficult to go to Heaven! He tells us “drifting along” with the culture (especially an evil culture like ours) is to find ourselves damned.
“Strive to enter by the narrow gate; for many, I say to you, shall seek to enter, and shall not be able.” Lk 13:24
And
"Many will say to me on that day, ‘Lord, Lord, did we not prophesy in your name and in your name drive out demons and in your name perform many miracles?’ Then I will tell them plainly, ‘I never knew you. Away from me, you evildoers!’ Matt 7:22-23
And many other places, aside.
We don’t typically tell people to “strive” to do easy things, nor are easy things those that “many” try to do “and shall not be able.”
This accords with the teaching of the doctors of our Church (see St. Augustine, who called mankind a
massa damnata, of the martyrs (see St. Cyprian), Infallible Ecumenical Councils (see Council of Florence, which said "those not living in the Catholic Church…will depart into ‘everlasting fire’
Cantate Domino]) of the past, and even of Vatican Two which declared,
"very often, deceived by the Evil One, men have become vain in their reasonings, have exchanged the truth of God for a lie and served the world rather than the Creator… To procure… the salvation of all these, the Church… takes zealous care to foster the missions. (LG 16) (in other words, these people need to convert to be saved).
Mother Mary also disagrees with you (see her revelation at Fatima) as does the revelation Jesus gave to St. Faustina (of Divine Mercy fame). Jesus told the saint,
“Souls perish in spite of My bitter passion. I am giving them the last hope of salvation; that is the Feast of My Mercy. If they will not adore My mercy, they will perish for all eternity.”
He also showed Faustina how immense Hell is.
