Some people could bet without even knowing the amount of time and money they have invested in gambling which could look obvious and call for estimation. I gamble a lot and sometimes I don't even know if it's becoming excess not.
Anything like excess gambling?
Two things they could be enjoying the game or they are trying to recover their losses, if they are doing this for fun and they are putting only excess money, there's nothing wrong with this, but if they are neglecting their homes and they are losing money then excess in gambling is on it's worse and should be dealt with immediately, this is dangerous it's bad for mental health and financial status.
