Why many people lost their sleepI am seeing many people irrespective of age spend their nights without normal sleeping. If aged there may be problems or worries but that not prolong for more than two days. This sleepless nights make others not to sleep either by disturbed or worried on their such situation.
I have seen an aged couple woke in the early morning daily by 4.00 am as if they have some work engagement. This may be their practice but will their health got not affected.
