Srimad Bhagavatam 7.6.6
puṁso varṣa-śataṁ hy āyus
tad-ardhaṁ cājitātmanaḥ
niṣphalaṁ yad asau rātryāṁ
śete ’ndhaṁ prāpitas tamaḥ
Every human being has a maximum duration of life of one hundred years, but for one who cannot control his senses, half of those years are completely lost because at night he sleeps twelve hours, being covered by ignorance. Therefore such a person has a lifetime of only fifty years.
Srimad Bhagavatam 7.6.7
mugdhasya bālye kaiśore
krīḍato yāti viṁśatiḥ
jarayā grasta-dehasya
yāty akalpasya viṁśatiḥ
In the tender age of childhood, when everyone is bewildered, one passes ten years. Similarly, in boyhood, engaged in sporting and playing, one passes another ten years. In this way, twenty years are wasted. Similarly, in old age, when one is an invalid, unable to perform even material activities, one passes another twenty years wastefully.
Srimad Bhagavatam 7.6.8
durāpūreṇa kāmena
mohena ca balīyasā
śeṣaṁ gṛheṣu saktasya
pramattasyāpayāti hi
One whose mind and senses are uncontrolled becomes increasingly attached to family life because of insatiable lusty desires and very strong illusion. In such a madman’s life, the remaining years are also wasted because even during those years he cannot engage himself in devotional service.
Srimad Bhagavatam 7.6.9
ko gṛheṣu pumān saktam
ātmānam ajitendriyaḥ
sneha-pāśair dṛḍhair baddham
utsaheta vimocitum
What person too attached to household life due to being unable to control his senses can liberate himself? An attached householder is bound very strongly by ropes of affection for his family [wife, children and other relatives].
