Paradigm Shift
Most will immediately think that going back to college at age 50 is an expensive luxury, right? Read On.
A University Lifestyle may be a lower cost, higher quality lifestyle option than many think.

Half the battle is the "cost of living" on campus.
A college student's cost of living is notoriously inexpensive! Where can you live, including housing, insurance, transportation, food and entertainment for less that $1,000 per month? This is close to the national poverty level and about the same as last years average social security income.
Look closer at Collegeboard.coms, Trends in College Pricing , and look at the "Public 4 Year, On Campus" budget as an example. Room and board, transportation and other expenses total $11,246 ($8193+$1079+$1974). I checked on the required student insurance, and found that it is less than $1000/year!

How can it be so cheap? You share! Want to help the environment and reduce your carbon footprint? Move back to campus!

Will I have to live in a dump? No! Things have changed. Examples are at American Campus Communities.

Will I have to share an apartment with 20 year olds? Will I live on a dorm floor with people running up and down the halls all hours of the night?

No, that is what UL does. We introduce and help Baby Boomers find compatible room mates and help select locations that group other UL students close together. UL forms social communities of like minded baby boomers on or near campuses. Would you rather share a 4 bedroom house? UL can point you in the right direction and can normally negotiate better rates because landlords appreciate renting to mature adult college students over younger students.

So, you have a great environment to live in, that is inexpensive.

The second half of the battle is tuition, fees and books.
One of the lower cost choices is 4 year public universities. Referring back to Trends in College Pricing , average tuition and books cost $7020+$1122=$8142. UL works as a peer group to find lower cost options. For example, some may take some of their classes through a concurrent enrollment program, where you take the regular on campus classes, with approvals,  for much less than normal tuition. Here is an example that allows you to take up to 10 units(2-5 unit classes) for
$1380 at UCR concurrent enrollment At age 50, with a low cost of living, a great lifestyle, and a UL community that is working on saving the world, are you really in a hurry to graduate?
