TimeLeft version 2.14
=====================
TimeLeft uses a piecewise linear approximation to predict life expectancy
and the probability of death within one year, given a birth date and sex.  The
approximation is based on Social Security actuarial data from 2016 C.E. for the
entire USA population.  The life expectancy and probability of death are
updated once per second, so you can see your life expectancy go up as you
age (at least if you are over about 40 years old).

TimeLeft is Copyright © 2019 by Ron Charlton.  You may distribute its setup
files freely.

TimeLeft is available for Microsoft Windows only.

You may update file "LifeExpectancyData.txt" with new data.  It is in the
folder where you installed TimeLeft (the default folder is
"C:\Program Files\TimeLeft").  The file contains a web address for the
source of its data.  The file's formatting rules follow:

The data file may contain blank or whitespace lines, or lines where
the first non-whitespace character is "#", indicating a comment.
Data lines must contain seven numbers (separated by any combination of
spaces and tabs) that can be interpreted as double precision floating point.
Some examples are: 34  4.56  0.0145, and so on. The numbers, all (except
probabilities) measured in years, must be
	1) age
	2) male probability of death within one year
	3) number of males surviving out of 100,000 born alive
	4) male life expectancy for that age
	5) female probability of death within one year
	6) number of females surviving out of 100,000 born alive
	7) female life expectancy for that age

Columns 3 and 6 are not used but are required.  They may be "0".

Data lines may end in a comment, demarcated by "#".

The file can contain any number of data lines (greater than one) and
any number of comment and blank lines.  The ages must
increase monotonically (but not necessarily linearly) in the file.

WARNING: Your edited file will be lost if you re-install or repair TimeLeft.
Keep a copy of your edited file in a separate folder.
