Life insurance at 18 yrs old, wdyt?

Hello po! 18 years old po ako rn and sabi po kasi ng mga kapatid ko is better mag start ng life insurance early kasi mas mura pa. Ano po kaya magandang life insurance na option? Preferablly yung pang long term na po sana. Any thoughts? Im still a 1st year college student, school allowance only.
